Whose platform is it? It's the users that make the forum valuable. Anyone can administrate a web forum. The individuals and communities should decide what speech is acceptable for them, not some unaccountable bureaucrats.
I think there is a time and place for insults and flamewars. Maybe not everywhere all the time, but what you are seeing on the web today is selective enforcement of "politeness" and "civility" rules to benefit whatever side of the "flamewar" that the moderators approve of.
HN is a good forum insofar as the users think that admins enforce reasonable rules and users agree to abide by those rules and not evade bans. On HN, moderation is rather sophisticated and neutral. When that changes I'll leave.
