If he’s a Nazi, I wouldn’t be part of that, but his freedom of speech is something that appears in need of protection.
Freedom of speech is limited by criminal laws. Just as you can get charged for slandering you will get charged for denying the Holocaust (here in Germany and AFAIK in Austria).
My preliminary look at his writings through Google shows no Nazi writings.
Can anyone come up with them and a link?
He still has a freedom of speech issue as far as I can see, regardless of what he says and what I’ve seen so far relates directly to abortion in his previous writings.
