As a gay dude myself, idt this is too bad. He's just listing preferences, he's not being offensive about it. If what he listed is wrong, then is it wrong for me to be gay because I'm being sexist by excluding women?

I actually prefer people list their preferences up front, that way that's no disappointment later.

For example, I can think a straight guy is cute, but I'm not personally attracted to straight guys, I find it unattractive, because I know they're not interested (in addition to hetero culture, chest beating etc that is just gross).

Easier for someone to say "not into short guys" up front cause then I just skip over them rather than interact and have awkwardness later on.
