I've never been to Europe. Are the racists just like this online or are they like this in-person, too? In the US, whites are only like this around other whites they trust. They become flustered when they encounter PoC and we're "well-spoken" and other passive-aggressive bullshit backhanded comments.
But even neo-nazis and klansmen know not to be too obvious with their comments in real life, even around other racists.
