It's hard to think of a more obvious violation than that one. Moderating such comments has zero to do with your opinions. We don't know or care what your opinions are.
I think it is a pretty reasonable response to the type of comment that was directed at me. ("you, sir, are a fire. in dumpster. omg."). I don't think you will find a single instance of me insulting anybody without them directing hate and insults against me.
Yet somehow you protect those people and not me. Sorry I can not respect you for that.
You seem to be saying it was ok for you to break the guidelines because someone else did it first. That's not how it works. It always feels like the other person started it and did worse, so that approach is a recipe for a downward spiral: https://hn.algolia.com/?query=downward%20spiral%20by:dang&da...
If you feel like you're personally being singled out for more stringent moderation, that's an illusion. I don't recognize your username (nor most usernames on HN). It's true that I banned you where I only warned the other user (https://news.ycombinator.com/item?id=30856521) but that's I looked up the history and saw that you'd been warned (and indeed, banned) more than once before, and because your account was considerably more abusive overall.
If the other user continues to break the site guidelines we will end up banning them also.
