The interview doesn't really go into much...
I can see a reason for some advocacy groups, but the name of that one puts me off pretty much immediately.
Father's rights, for instance.

As to single sex gyms, I think they should be doable. I get self conscious, personally. Well, a lot of it's the same reasons women prefer women's gyms.

Some of the things are odd, like the guy denying that white male privledge exists.
All I can think on that is 'Try being a native cripple some time, asshole.'
