"Self-awareness is not your strong point" was an egregious personal attack. You can't do that here. Ditto for "You aren't as complicated as you think you are", "I'm pointing out what you are.", and plenty of other things you posted in this thread. If I look at those comments cumulatively, you crossed the line very badly. The fact that someone else was also behaving badly doesn't change that.

The rule is to stick to the rules (https://news.ycombinator.com/newsguidelines.html) regardless of what someone else does. That's how rules work, no? No one's asking you to remain robotic, but you do need to remain respectful.
