Are you on something? From what can see and read, it is anti-French, German and (now) Belgian-ism, not Europe as a whole. And even if it were, why would that be self-hatred?
I view it differently. My ancestors detested the Old Europe they came from. They left the tyranny of Europe, the poverty of Europe, the hypocrisy of Europe behind and never looked back.
My grand-uncle (whose mother came from Bavaria and who was 10 when she did so) fought in Europe and was of the opinion that we should have saved some of our nukes for France, Germany, and Russia.
