Yeah, don't take it seriously. If he kept bashing homosexuals throughout the book then that's a different story. Keep reading, I'm half way done and got it a few hours ago. Great read.
I've met this guy before and you hit the nail. He would say that exact line verbatim to every girl and it just sounded so repetitive and ungenuine. He's a good guy, and I'm sure he gets laid. But he's not a "max level PUA", he's very technical and "stiff".
