I don't think she's arguing that you should be friends with weev -- you're right, neither of you are in the same tribe and neither of you want to be in a tribe with each other. She's arguing that since she's already in a tribe with weev that she's better off maintaining a relationship with him rather than trying to kick him out of their common tribe or, more likely, removing herself from the tribe, as that seems to be how that sort of thing typically ends up.

Nowhere in this paean to St. Augustine is there argument or evidence that all this lovey-dovey changed anyone's opinions one iota.

Outliers? Maybe so. From a personal perspective, though, my views on most political and social things have changed completely over the past 10 years, and I'm disgusted by some of the positions I used to argue pretty strongly for. I can definitely say that I would not have been able to make that change if I wasn't around people who took other viewpoints and, often unintentionally, educated me on a lot of stuff.

I dunno. I don't think I'd be friends with weev, but I do think that long-lasting social change has to include changing peoples' minds.
