Neither do I....
Usually its just guys that look after themselves, care about their appearance a lot, are interested in clothes, keeping fit etc that get called gay. Those aren't traditionally masculine values, so people (wrongly) assume that if you like clothes, you like cock.
Just to make it clear, I wasn't implying that all gays talk high pitched. I believe you hit the nail on the head with that post. And apparently working out is extremely manly while running is wimpy. I won't get off topic, but stereotypes can really go way too far.
