Can America/UN really allow Europe to hate on Muslims and Jews?

Only 80 years after the Holocaust can America and the UN really allow the EU/Europe tp hate on Jews and Muslims? The far right has gained too much influence in Europe. From anti Islam to out right anti semitism. Countries like Hungary, Sweden, Austria, Italy, Norway, Finland, Netherlands, France, Belgium, Czech Republic, Slovakia, Serbia, Croatia, Switzerland, Greece and Russia have all started to turn on Africans, Muslims, Jews, Gypsies and other foreigners. Can we really allow this as Americans?! How can we stop the Europeans from being racist again.
