Hitler wanted massive numbers of Jewish deaths. The Jews were no threat to him or their fellow non-Jewish Germans.
The Jews weren't strapping bombs to their bodies to blow up people across the globe. The Jews weren't mowing people down with motor vehicles, and weren't shooting and stabbing innocent civilians. He just made them scapegoats for Germany's economic problems.
Marine Le Pen isn't advocating harm to anyone, she only recognizes that the people of France weren't consulted regarding the formation of the EU and the ending of borders, thus allowing the massive influx of migrating Islamists. She can see (as others can) that huge numbers of Islamists, coupled with their high birthrate would gradually change their free secular nation into an Islamic theocracy with the accompanying oppression, persecution, hatred and violence towards non-Muslims.
Please point to those Islamic countries in which non-Muslims not only thrive, but flourish and are treated as complete equals in all facets of Islamic society.
