I tried to discuss this here and on the other site. I provided many links to articles and quotes from books written on this very subject. Each time I was shut down by people who said that what is going on in Europe is fake news and they poo-poo'ed every incident of anti-semitism in France that I cited.
I'm guessing, without actually seeing any sources, that you quoted alt-right nonsense.
But, I will stand to be corrected.
