You've clearly been breaking the rules repeatedly—this is not a borderline call. For example, https://news.ycombinator.com/item?id=30577434 was certainly an attack by the standard we apply here. If it doesn't fit your own definition of the word, that's fine; but it's the kind of thing we ban accounts for, so we need you to stop posting like that if you want to keep commenting on HN.
The rules apply regardless of how badly others are behaving. It always feels like the other person started it and did worse—this perception is hard-wired in all of us, so to use it as a justification guarantees a downward spiral.

The fact that you had to ban his account pretty much proves my point.

Just calling things what they are.

There is no attack here, not even the mildest hostility. Pointing out that someone is talking out of their ass isn’t an “attack”.
