I've also had the reverse happen to me where some of my more effeminate gay friends have accused me of being a closet case and a homophobe because I'm not as outwardly flamboyant as them. It gets pretty obnoxious because I'm just being myself and they keep wanting to treat me like I'm hiding something when I am not. Or they start projecting and saying stuff like "you just don't want to be seen with gay people like us" and crap like that. They aren't willing to accept me for who I am even though I've countless times accepted them for who they are. Not all gay men are cosmo sipping, madonna worshipping, sassy "queens". It's kind of ridiculous when see some gay guys go out of their way to live up to a plastic stereotype of gay men.

I am very sensitive to that sort of thing.
Your friends sound annoying to me. There were some pretty conservative gay guys in my circle of friends, but they still held a witty tongue and they were funny and creative, but not flamboyant about it. We still knew them to be gay and loved them for them. Sometimes, when we think that we are coming across a certain way, we aren't unfortunately. But other times people think something and want to continue with thinking it, and if they want to think that you are not being yourself or that you are ashamed to be seen with them, then they will sadly
