Serious question, because I don't know the answer:

What qualifies him as an expert?

I ask because his own "about me" section just lists what he's published and his appearances, and about his activism. So going by only that, he's clearly expert in giving his opinions, but I missed what ever experience and/or training he has that informs those opinions.
