Open Forum: Do Gays Have Different Mannerisms?

If someone paints the gay community with a broad brush they are labeled as being insensitive, ignorant, or worse yet homophobic. To suggest that all gay males are effeminate, or that all lesbians are butch leaves out many people who do not fit these stereotypical behaviors.

But is there some truth to the stereotype? More and more research is coming out to suggest there are some genetic differences among most queer people. Gay men typically have a higher pitched voice, raised eyebrows, bigger lips, and have feminine expressions and mannerisms whereas lesbians tend to be on the opposite spectrum with deeper voices, lower eyebrows, and a more masculine disposition.

While this may not be true for all people who self identify as queer, is it possible there is a feminization and masculinization of the brain that is occurring which alters the way we behave from heterosexual and cissexual people?
