Buzzer, my problem is not with the "acting" part but with the fact that it equates "straight" with "masculine" and worse - with "not gay". No gay man should describe himself as "not gay". That's spitting in the face of everything about the fight for equality. It ABSOLUTELY doesn't matter what random ignorant breeders think when they hear "gay". The folks who use "straight acting" are gay men communicating with other gay men. The term really has nothing to do with straights' perception, even if some of them might have a notion of what "acting gay" is.
