I don't think it really matters. I believe what is more important is to ask ourselves why we find it so "offensive" for a man to be "swishy" or "effeminate." I think a lot of gay men find it difficult to deal with effeminate gay guys because they think that str8 people think that ALL gay men are effeminate and therefore "not manly." What is really unfortunate about this way of thinking is it gives credence to the archaic notion that gender is biological. Gender and gender expression are not based in biology.
What do I mean by all this? The fact that you had issues with these supposed "effeminate" men in the restaurant "openly" acting flamboyantly says more about your insecurities about how people perceive you as a gay man. I don't mean to say this to you in a mean-spirited way, and I hope you do not take it as such. There are always going to be ignorant assholes who believe that all groups are one way or another; there's nothing you can do to stop that except to be yourself and prove them wrong.
As for the effeminate gay dudes, consider our world that much richer for having people in it who defy definition, labels, and boxes. Next time, send them a martini and tell them to keep the flame burning bright!
Cheers!
While I understand whee you're coming from with the "insecruties issue", there are other aspects to this arguement as well. Some "femmies" are not like that naturally (ie, thats not there actul pesonality), they just need to act like that for the need to stand out and be different (even though thats not them), which is totally unnecesary. I mean, yes be yourself, but shoving something in other peoples' face unnecessarily is annoying and immature. Now, I'm not saying all "femmies" are like that. Some gays are truly effeminate like that at heart, and don't try to push it in faces like some guys do. The one experience I have with this group, my freshman year in high school, I was at drama, and the most effeminate gay guy in school who was known for it was there, standing (very tall). A girl in the back asked if he could move over, she couldn't see. He just went (really high pitched complainy OMG voice) "But, I'm being SEXXXXXXXIIIIIIIIIIIIIIIIIIII-UH!!!!!!!!!!!!!!!!!", and just stood there. That first incident wiht me caused me to not like it, and it just annoys me. ANother thing, I've always had a thing for football players (the complete opposite, so, I dunno, just wanted ot say something...
