When I was younger I made a comment around my aunt (who’s a bit over the cuckoo’s nest as it is) about such and such male actor is a good looking man. (I don’t remember who it was or the exact phrasing I used.) Years afterwards, on her bad days she would rant a bit, would obsess on that comment. To this day certain family members treat that subject with kid gloves. lol I never saw what the big deal was. If I can notice physically attractive qualities in myself than why wouldn’t I be able to in others, type of thing?
Brad Pitt is a good looking guy.
Yeah, it's a bit of a silly kind of homophobia. If you're able to say "That [guy] looks ugly" (which everyone expects straight men to be able to do) then you're able to discern aesthetic qualities about other guys, and it stands to reason that you'll be able to weigh in on positive qualities as well.
To the original question, I dunno. Personality is a big deal for me, and I'm just not really in the know about many celebrity personas. They're all just faces to me. If my hypothetical gay self is into the same type of guy as the type of girl I'm into, then it'd be somebody who's confident, outgoing, and smarter than average. I guess if Ryan Gosling (sp?) fits that bill, then I'd be down.
