You may have heard of the “Countering Violent Extremism” program under DHS.
They’ve deployed the tactics used to fight terrorists against domestic citizens. For example, incels. When I posted on the web forum incels dot is, I didn’t know it was Department of Homeland Security operation against men who say they are romantically deprived. I didn’t know I was interacting with larping feds who encourage extremist rhetoric. Consequently I was put on a watchlist and am subject to intrusive monitoring.
But that's more work than they need to do to discredit or lock someone up. It makes no sense for them to do that to you. It's much more likely you have a health condition.
