Almost two million Poles, 400K Gypsies. Maybe not "millions" of gay men, but they were specifically targeted for extermination and the nazis killed all those they could get their hands on. The insistence on the 6 million ignores 2 million others who were systematically exterminated in the same locations because of their belonging to certain groups. The jews were not the only group that was specifically targeted for extermination.

A society committed to the notion that government is always bad will have bad government. And it doesn't have to be that way. — Paul Krugman
