I'm talking like 28 Days Later infection rage. It comes almost immediately.

You can be the friendliest, most open-minded person on the planet and people will still rip your head off if you believe in TRP. Of course, if you sprinkle truths into casual conversation they'll typically genuinely laugh and say it's kinda true. But never EVER say what it's called. Once/If they find out where you're coming from you can just sense the rage-filled disconnection from being their friends or even family almost immediately.

This same reaction tends to come from anyone regardless of gender or political alignments.
