Look, nobody takes 9/11 Truth seriously, but when you start telling people that the Holocaust is a fraud, or that a Jewish-conceived post WWII massacre of Germans killed more of them than they killed Jews, you'll rapidly find yourself persona non grata in most segments of American life: workplaces, churches, schools and universities, civic groups and on and on. Even in conservative families, Holocaust denial is associated with Nazism and antisemitism.  

And again, you need to understand that your "facts" are deeply, deeply flawed.  Your reasoning is based on flawed data. The figure of 300,000 you, yet again, tout as accurate is a total falsehood. The IRC never said this. All of your factual claims have been disputed and debunked. Didn't you study this stuff at Stanford? 

Educated people know that Holocaust denial is a fabric of lies, and even uneducated people find Nazis and antisemitism utterly repulsive.
