Ok, so, I don't know if anybody's already said this, since there's 11 pages of posts I don't have time to sort through.
I'm not defending the guy's overall views very far, but I do think that his words may have been taken out of context. From the blurb that I read (and I admit I may be missing some other comments or a greater context that is lost by only reading the one blurb), he is speaking specifically about which group he feels more personally threatened by, rather than who has a more negative effect on society. The context I'm reading from this is that he's expressing that he feels more threatened by gamers because they target him personally, whereas bikers do not threaten his person, despite their animosity towards him.
