In their small dim worldview anyone who is anti-abortion and anti-gay is a nazi.
They toss around the "N" word so casually that they don't realize how childish it makes them look. As the Jerusalem Post pointed out, if anything Ratzinger lived under Nazi oppression. I guess if he were pro-abortion he'd suddenly be seen as a victim of Nazism for doing the exact same things. It all boils down to abortion with them.
