The Holocaust happened, Nazis tried to eliminate Jews, Communists, Union members, Slavs, Romani, Republicans, LGB people, Soviet citizens etc. They slaughtered millions and millions of people through mass industrial slaughter. Even if you don't believe the numbers, Numbers don't really matter in the end. They did it, their goal was to completely eradicate these groups from the face of the earth and they tried as hardest as they could, men, women, children were murdered enmass in cold blooded slaughter.
Now the only thing I have a problem with, which is the exactly the same as Based Finklestein, is the "holocaust industry" and how the Holocaust is used to blackmail Western nations into supporting Israel and the Jewish community above all others minority groups and cover Israel's war-crimes and Nuclear proliferation. Also along with Finklestien, I find the way the Holocaust is exploited, to frankly be insulting to victims of the Holocaust especially when Israeli shows like Eretz Nehederet will openly make fun of the fact that a lot of the guilt tripping used against Westerners is done in bad faith to further Israeli interests.
I also find a lot of the arguments used by Holocaust industry types disingenuously. You can't compare what say, Israel is doing to the Nazis, because that's "Antisemitism", but then it's perfectly fine to compare Putin and Russia to Hitler? When technically Soviets/Russians were slaughtered in even higher numbers and were direct victims of the camps as well? How does that work?
