Out of curiosity, I checked the discussion in which you referred to by link. The person in question is not a developer or contributor, but appears to be passionate about the discussion. I don't think it's bad to have a difference of opinion, even among good friends. In addition, we can't always be right on every issue, and sometimes we have to "agree, to disagree".

The other person in that discussion on V's GitHub even apologized for appearing harsh, seems to have begged you to come back, and gave you a compliment.

Also deleting your part of the discussion also robs other readers from evaluating the full merits of your side. There will usually be people on your side of the discussion as well or see your point of view. I think you will find that overall and from what I've seen, people in the V community can be appreciative and welcoming, but like anywhere its a mix of different personalities and characters.

This user is not a member of the V team, and never contributed to the V project.

He enjoys language development and submits his feedback and ideas, discusses other ideas etc.

I do not work as a big censor and read every single of the thousands of messages, and I do not have time to do it.

That was a rhetorical question, I am not implying you should do anything. Thank you for the transparency.
