There it goes: you lose your temper while someone tries to explain why they're the exception to the rule, and before you know it, the old toxic personality has emerged to steer the moment into an emotional shipwreck. At least this time, you had the grace to apologize a few minutes later, but still.

Surely it's not THAT difficult to act like a human being instead of an asshole, but intolerance is the ulcer that flares up, the allergic reaction to the object of your prejudice. You can manage it, but you can't will it away. Word by word, deed by deed, you build your own life, determining whether that life is useful or useless to anyone else. Pissing people off -- what good does that do? Bringing other people down -- is that what it takes to make you feel alive?

(Sidebar: if your heroes are the talking heads on a screen, remember -- these are performers, paid to mouth whatever words are put in front of them. Their job is to make you, the audience, feel what they want you to feel.)

There's nothing very smart or very satisfying about gratuitous cruelty. It doesn't help anyone. Don't go there. Now for the hard part: you've gotta take your own advice.
