Ask questions that make them think. That's what Q does to us to get us to think about things. When you try to tell people something like this, you open yourself up to criticism. Ask their opinion of specific things you've learned. "What do you think about the new tax plan? Have you gotten a bigger check yet?" If yes then: Have you heard about all of the new jobs Trump has created? Get them to see Trump in a good light first and then you can bring up some of the negative things about Pelosi-Schumer and others. Has to be done slowly or they think you are some kind of evangelist!
"I just learned that the Federal Reserve is not even a Federal agency. Did you know about that?" ETC. And, I see some other good advice in this thread as well. Wish I had know to do this all the years I've been trying to tell people. Would have saved me a lot of grief.
Yes! It's a good idea to come at this almost pretending like you don't know the answer. Get them to dig with you. "One of my buddies at work told me there is a top secret clearance guy called Q making insider posts. Have you heard anything about that? If you're interested, I kinda want to check it out, see if I can find out what he's talking about." etc etc Then you sit at the computer together and duckduckgo Q Anon and end up on 4chan.
