I think I should clarify a bit.
I prefer masculine men, but I don't like when they use the phrase "straight-acting".
I also do not like when they put down other gay men that are "effeminant" or transgender people. Basically the guys that put down everyone else to make themselves look more normative and acceptable.
But yeah, being masculine and accepting of all type of other LBGT people is completely fine, and is a turn-on. And as far as friends go, I don't like hanging out with other gay guys that feel the need to scrutinize other's sexuality and behaviors, because it just shows how negative and insecure they are.
