I tend to have a similar mindset - I have an allergy to groupthink, and when I see groups of people saying false things, even if I generally normally agree with the spirit of the group, I have to at least 'fact check' with a response. But in this strange new bifurcated reality, you get pinned as 'Other' as in, I must be the 'Other side' and thus subject to to some sort of retaliation.

I don't get 'banned' but I get downvoted - as I did on this thread with no real explanation.

I have absolutely no problem with "Fact checking" because at least it shows the original thing. I have a big problem with shadow banning, deleting and outright banning. The latter is censorship.
