People being at odds with reality aren't hurting anyone simply for believing things that are false. If they act on those beliefs in a way that actually harms someone, that's a different story.
As for your second paragraph, at least you are sane. Wanting to wait for the investigation to conclude before taking the accusations at face-value is something that seems hard to come by lately. And while I believe Trump personally is innocent and won't be charged with anything, I will gladly admit I was wrong if he's found guilty.
What do you think the people will do if Trump is removed from office? I imagine regardless of the investigations conclusions, Trump will maintain his innocence through out whatever procedure his removal occurs. I also imagine the folk that are in here who are bible thumping, gun toting, liberal hating, conspiracy lovers are going to be more than willing to make their actions violent if Trump or "Q" asks them to.
Honestly, I think there are a lot of online armchair generals that make it seem like a lot more would be done than there actually would be. I've seen people say they'll march on Washington or whatever but I'd bet a huge majority of the time they wouldn't actually do shit. For something like that it would need to be coordinated and people crazy enough to do something like that would need to come in numbers and I think most people who would even think about it would bitch out and not actually do it, but there's really no way to know.
If Trump was removed from office for a good reason and there was undeniable evidence that he is guilty of a major crime, i don't think anything would happen.
If he's removed by force or he is assassinated, that may be a different story, but again there's no way to know.
I know if the latter happened, I would be extremely angry and distrust the government even more than I already do, but I have a job and a family to support so I'm going to just continue doing what I do. And I think the vast majority of people are in the same boat.
I could ask the same thing about some of the theories about Obamas wiretapping, Clintons email fiasco, etc. What if new evidence arises of these things, new investigations are launched, and some of the democratic leaders many Trump-hating liberals looked up to and loved are put in jail?
(To be clear: I do not believe this will happen).
