> When they're old they might become the new racist uncle

Honestly, that's what's got me concerned. Political mores are changing so fast and so constantly, and people are being so black-and-white about them, that it seems like the only "acceptable" position to some people is getting pretty close to a full-throated condemnation of everything and everyone that happened before they were born.

If it wasn't so easy to fail the purity tests, maybe fewer people would become Nazis (either out of ostracization or to troll purity the testers).
