Apologies---my intention was to signal that I wasn't interested in escalating the conversation or causing unpleasantness. I am completely happy to leave the last word to you.
Re "vandalism" and "being part of the community", thanks for your thoughts. I don't see myself at all as part of this community, but I do occasionally comment in it and on it. How is that possible? HN is a community of hackers and startup doers, and I once really was part of that (when I had the misfortune of being employed by a YC company); but a community is defined not just by collocation but by shared values & shared norms. Completely understandable if you'd rather I just buzzed off!
I understand the remainder of your comments, but I don't agree with them at all; to me, it is quite similar to the old bourgeois-liberal argument against antifa action, "you're just as bad as them!". In any case, it's completely understandable how & why you think that way, and I'm not interested in having a fight about it.
I will simply take the position that it is worse to arrogantly claim instant expertise than it is to (snarkily) criticize arrogance.
