Maybe it’s because we’re in the Trump era. I see the contagion of contentiousness everywhere. If we don’t all take responsibility for ourselves and stop blaming others, it won’t stop.
I think it is more than that. The membership here has become more liberal/left leaning and and very pc and sjw minded. For instance, I found the politics thread much more enjoyable when I was just about the only non-conservative in there. Now it seems as if you either have to follow the liberal mindset(woke) or you’re offensive.
