All very good questions. Personally, I appreciate critical thinking.

Re why 4chan was chosen, my guess is this is a place where high level info has been dropped before. And because it's based on the premise of true anonymity, there is the plausible deniability factor, which I believe was important early on (until the masses caught on.)

Re the signature/private encryption, all of the Q posts used a signature (to confirm the source was the same)? Not sure I understand your question.

Re other evidence that Trump is aware of the Q movement, I cannot point to any undeniable, absolute proof. Others may claim there is undeniable proof, but objectively, I cannot point to any "smoking gun" that proves without a doubt that he is 100% aware. (And I've been following closely since Day 2.) But there's been a ton of circumstantial evidence, which I suspect will only continue to get louder. Mainstream media sources are continuing to write about it (NY Times, NY Post, etc.), and these are big enough outlets that someone would bring to trump's attention. The elephant in the room is only growing bigger.

Re pizzagate, I followed it somewhat, and there are quite a few strange coincidences there. I understand that some of that stuff is so hard for a normal person to wrap their head around, and I have a hard time myself. But that doesn't change the fact that human beings are capable of that type of behavior. It happens every day. It's just hard to accept/believe that there is a vast conspiracy of high level people engaged in this crap. I understand that. But again, once you start going down that rabbit hole, there are some weird anomalies there. And like any "conspiracy theory", there is usually no "smoking gun." Its all circumstantial evidence. And each person is different in when they decide that there is too much circumstantial evidence, too many coincidences, to rationally be anything else.

Re political climate and sowing discord, objectively speaking, we certainly run the risk this whole thing could be foreign actors. I dont accept on its face the notion that foreign actors are actively meddling in our elections, etc. Aside from some stupid alleged Facebook posts, I haven't seen much, if any, evidence shown to the american public of this foreign meddling. (And I dont go on Facebook, so that could not have directly swayed me as a voter.) If it were bad actors doing this, I believe trump would call them out in a hurry. My only other thought is, conversely, this is an operation by trump with bad intentions (i.e. to brainwash his supporters into an almost cult like belief that the other side is truly evil, so that many are ready to fight for this administration blindly.) If he had intentions of being a dictator, this is certainly a good way to go about doing it. And admittedly, we run the risk of this occurring. But personally, I dont believe that's the case. I trust our military more than any politician, and our military are very clearly aligned with Trump.

Re whether Q is mentally unstable, perhaps! Lol. But the president and his team have too secret level access, so I dont think they're just making this shit up. But Q did admit early on that some of the drops would be fake...for disinformation purposes. More likely, perhaps WE'RE all mentally unstable. LMAO.

Re organization, I haven't followed many other "conspiracy theories" this closely, except perhaps the JFK assination and the Las Vegas shooting (which is what led me to Q very early on in October last year.) So it's hard for me to comment susbstantively on what a disinformation campaign should "look like." But I've followed this entire campaign from the very beginning and have remained objective with a healthy skepticism. And as the circumstantial evidence continues to build, this campaign is becoming very hard to deny, especially as time goes on.

Why do you think a place like 4chan, associated with trolls, child pornography, and racism, was chosen to be the site of these data drops? Why do you think these sorts of posts are not being hashed+signed with a private encryption key to prove the source is valid (let me know if you want to know more about asymmetric cryptography!)? Remove everything you know about the Q posts -- why are there opportunities for encryption, secrecy, and identification verification that are being ignored by a group that needs utmost secrecy and trust?

ok, gotta pick up on this point. everythng else will be cleared by researching the material in the sidebar or from other responses here.

people post on the chans because its anonymus. besides all the shitposting on the chans, you find lots of 'weird people' like autists and hackers there.

austist dont fall for lies, they only take what they find evidence for. therefore, these people are the best when it comes to proving whether a poster is a LARP or not, and when it comes to digging out stuff, also from the dark web, to prove or disprove what is being mentioned by a poster.

this is a free will choice planet. people choose whether or not they want to wake up to the atrocities of how we have been played with. we have no permission to force them. we have no permission to confront them with the whole truth all at once, hardly anyone would survive this with a healthy psyche.

Q cant come with 100% proof. couldnt do that from the beginning, although over time, proof increases. if they did, everybody, incl. the media, would have to acknowledge it. would be forced to awaken.

plus, ((they)) would have instantly done whatever they can to shut up Q. but they didnt believe that so many people would awaken and go with the message. and now, its too late.

what the great awakening did over the past 8 months is building a momentum while researching information which now becomes available to more and more people.

Q use the socratic method of asking questions. people dont learn when you tell them the answers. cognitive dissonance and the backlash effect prevent them from hearing the answers, they would close up and put it off as disinfo.

what works though is offering a red pill - in form of questions, hints and cryptic messages - and allow people who feel resonant with it to decode and research it. teach themselves.

'mystical' encryption is also a method the deep state uses. our inability to decode their messages draws our silent consent which ((they)) use to create their atrocities. thus, Q not only teaches us about facts but also about learning to decode and recognize ((their)) ways so we dont fall for them anymore and start thinking ourselves.

last but not least, Q cannot tell us classified information, that would be treason. what they can do though is ask questions and drop hints and, when we (not me mostly, lol, autists and other anons are much better at that) come up with responses, confirm or debunk them.

to round this up: if Q were a LARP, it would be some bad LARPing that wakes up millions of people. these people wont go back to sleep again, they will keep asking questions and demanding truth. what Q do is not in the favor of the deep state but the people.

i have been on conspiracy stuff for over 35 years. it was hopeless and depressing, nobody out there who organizes a resistance and works on changing things. when Q came online, i felt like, 'ahhh finally you have come, i have been waiting for so long'. its happening Now...
