I worked for a hetero-hating uber-butch dyke a few years ago. It used it's sexual choice as a shield for EVERYTHING, as it was incompetent at everything from managing people to pouring a glass of water. This life form absolutely thought it was a separate race and was very vocal in admitting it. It thought it was a species that needed legal protections.
p.s. I quit that job without having another one lined up as I could not stand being anywhere near that freak.
Those kind of females commonly hate men, as opposed to heterosexuals. That's because, contrary to popular belief, lesbianism commonly stems from a serious problem in a relationship with an important male figure in the affected individual's life. Most lesbians have had sexual relationships with males, and rejected them, turning to women as a more comfortable alternative. The pathogenesis of lesbianism - yes, pathogenesis - is better understood in general than that of male homosexuality. They are not mirror images of each other in that regard.
BTW, the incidence of lesbianism in any population is much lower than the incidence of male homosexuality.
