Just the other day, I decided not to go to a small event for exactly this reason, because I knew that one or two people there believed some fringe stuff. I don't, but being somewhere where they aren't kicked out is professional suicide for someone in my position. One never knows these days who might be recording and has to live his life as though it were being constantly observed.
Edit: to clarify, by fringe stuff, I mean that some believe that the election was stolen from Trump. I don't and have convinced others that it was not, but I guess I can't do that anymore.
