I think some people are very confrontational or are hugely invested in showing they are 'right' on certain topics that have emotional weight for them. Sometimes I find there are certain comments that I quite like from a member but at the same time there are other comments that I want to confront in an unproductive way or I spend too much time thinking about them. I have . blocked people like this only to find out later they had gotten themselves suspended and i was just glad that I wasn't aware of the situations that led to that anymore...

I appreciate PC for many reasons but it is also a way for people to play out their worst impulses at times, just like any human interaction can be.
