If you say you ban people for telling the truth I'll consider to not post on this platform and contribute in the future. Because we are getting close to censorship if you despite someone explaining himself threatening with banning them for a personal attack which it wasn't in this case and even the OP agrees to that if you follow the course of this discussion.

>It's easy to make your substantive points without declaring others to be stupid, so please do that instead.

I agree with you on that point, instead of calling someone else stupid for poor judgement I'll instead call their argument stupid or to not cause any friction "poor judgement" instead and explain why I think that to keep room for a discussion on the argument and not the author.

Thank you for your input.

We don't ban people for telling the truth, we ban them for breaking the site guidelines. Fortunately, it's possible to tell the truth without breaking the site guidelines, so there need be no conflict.

Calling arguments stupid still breaks the site guidelines though. Would you mind reviewing them? I think it might help: https://news.ycombinator.com/newsguidelines.html.
