imo, 'weird' wasn't the correct word, nor was it strong enough
That's the thing, though: against regular people, it's the mildest of insults if it's even an insult at all.
Against fascists, thought, it's DEVASTATINGLY effective and here's why:
Fascist movements depend on being absolutely convinced that they're the only sane and normal ones in a world gone mad because everyone else is an immoral weirdo. That's how they justify all of their atrocities, and it's what their entire shared identity is about.
When you point out what weirdos their leaders are, that makes them doubt EVERYTHING about them. After all, in their world view, all weirdos are insane and immoral and all righteous people are normal.
