I think the distinction is behavior, not "people they don't like". Witch hunts are against the guidelines of reddit; that's not a secret. Whether you support Trump or not isn't relevant, if you're on a witch hunt. Likewise, posting personal information has, from almost the very beginning of reddit, been the one cardinal sin. The sin that'll get you banned or a subreddit closed down.
That's what spez was responding to. He did it in a terribly immature way that I could never condone (unless it were really funny, like this, in which case, I think it's hilarious). But, it was not a random "I don't like this group" situation, and to frame it that way is to manipulate the narrative. The behavior in question was a witch hunt, and against reddit rules; the witch hunt started because a subreddit was banned for posting (tons of!) personal information and launching a witch hunt against a random restaurant and bar and its owners. Again, that's clearly against reddit rules. Those rules are reasonable, and if someone doesn't like them, they should take their shit elsewhere.
It's not about not liking The_Donald. Nobody likes The_Donald, but reddit has always been more than fair in dealing with all of their bullshit; the vote brigades (against reddit rules), the orchestrated abuse of other subs and moderators and users, etc. Large swaths of them probably should have been banned months ago. But, Steve has always been slow to ban. Probably to a fault. When you fail to ban folks like this you breed a community of people like this, who feel entitled to be abusive without response.
