This is awesome and I wish I had the courage to do it.
My experience is, in the USA, eventually nearly every meetup is ruined by politics. Eventually someone says something unintentionally trigging someone else and then off it goes.
I haven't had that experience too often here in New England. Though I'm typically involved with specific hobby based groups. Usually politics are avoided and if someone insists they are basically politely ignored.
In my experience honestly this isn’t common. People really hate disagreeing IRL and can often sniff out when a disagreement is happening that’s just a form of trying to control the environment unnecessarily due to one’s personal issues. However it is important not to be too tolerant to straight up antisocial behavior that uses “don’t be political” as a form of self defense too. I’ve definitely had to kick out guys who did shit like treat women in the group like unwilling romantic targets even after being turned down, or guys who take being turned down personally and then tried to call the woman a fat cow over it who then also tried to use “stop being sensitive and political” as a cover for just being a poorly socialized male.
