Europe has been categorically worse, considering the scale of antisemitism, ie. the Holocaust.

Someone else being just as bad/worse is not a valid excuse.

My point is that racism and right-wing nationalism isn't something that somehow started in Europe in the last couple of decades and then came to the US. It's been there since the beginning on both sides of the Atlantic, and systematic racism in the US has been a thing since before the founding fathers put ink to paper.

In addition, you can't just say "Europe" as one unit. There are vast cultural differences between even neighboring countries. Europe does not act as one united country, it's a patchwork of localized opinions and cultures.

The OP said it was a "purely American phenomenon." I proved it's not. I don't know what you're arguing, it's not relevant at all.
