Every other time I’ve encountered this argument, it’s been an argument in favor of racism and xenophobia, often a Nazbol argument like “socialism only works if no diversity.” It’s my instinct to refuse it.
But I couldn’t deny that, American conservatives and liberals + leftists, on the mental level, live in different realities, with not only different core values and worries, but different ideas of what is actually happening (and no, I actively believe American leftists do not live in a fundamentally different reality from American liberals the way conservatives do from liberals + leftists.)
In the context of Lemmy, my best explanation is that tankies hate Orwell.
