You can't attack another user like that on this site, and we ban accounts that do, so please don't do it again.
If you'd please review https://news.ycombinator.com/newsguidelines.html and stick to the rules when posting here, we'd appreciate it.
of course it is also possible to just argue against somebody with less emotions and being more polite, without saying such things which I will 100% try in the future! my personal style is also harsh but I never intend to be offensive and surely have zero joy in attacking, insulting or making other people small
harsh honesty is difficult to separate from attacks so it is legit to ban this style altogether
