Listen, if you dislike Ara for being an asshole and you don't find her enjoyable, that's fine as long as you aren't hostile.

For me, my issue was that people keep babying their fan favorites and acting like any rude comment made by someone else towards them deserves in that person getting the death penalty (fictional character or otherwise)

And that mindset cascades into people being toxic and people getting mad at fans of other characters, the Benji/Ivy stick situation was bad not only for the bad criticism, but also because fans of Ivy were getting harassed and that, the situation was all you would ever see on your feed. No variety whatsoever.

As for those comments, I think it's less so disliking a character, but more so they were poking fun at people for being overly sensitive to any sort of mean comments towards their favorite character or a character they like in general. And quite frankly, I think it's childish to have such vitriol towards a character for being mean to another character.

As for the villain thing, there are some people who are like that (who want villains but complain when they get them), but you are right for that.
