One thing I've noticed is that a fair number of people seemingly can't tell the difference between attacking an argument and attacking an arguer.

There's also a number of people who don't seem to be willing to actually discuss anything, because falling back on hater/white knight/whatever other meme of the week is so much easier.

I'm not going to drop names for either, but both are a big part of why I just can't be bothered to do much more than make bad jokes anymore. There doesn't feel like much point in trying to have a discussion in good faith when I can't really expect the other person to respond in kind.
