If we're talking about conversations in "meat space", 100% agree with you. It pays dividends to stay away from controversy, politics and whatever one might define as truth being repressed by the zeitgeist. People mostly just want to have a good time, laugh and reaffirm the feeling of connection with each other. That's far more important than making a point.

That said, spaces like these are for expressions of radical thought imo, at least for some people. If it angers you to see it in your timeline, maybe that was the point. To make you feel something, and start to form opinions about things which are important to others.
You are free at any time to change the channel on that.
