Redit isn't a community. It's a bunch of communities. Most of them, I more or less dislike, for various overlapping sets of reasons. But I support freedom of speech. Everyone is free to ignore whatever they dislike.

Also, in such communities, strong anonymity is prudent. It does protect griefers from consequences, I admit. But more importantly, it protects all users from meatspace risks.

Edit: This is an old discussion. Especially if one replaces "Redit" with "Usenet".
