Just because you're out and abot with your "Lesbian friends" (are they, really? Or, are they just saying that to avoid your romantic predations?) doesn't give you the right to broadcast the nature of their private conversations. For your information, Transvestism and Transsexualism are relatively new phenomena within society. Transsexuals now have a fast track to becoming "female"' or "male". I use inverted commas because Trans-sexuals, whichever sex they wish to transition to, do not become that sex. They are simply a man/woman who really wishes they'd been born male/female. Why? Well, because it takes more than a set of gender specific genitals to become male or female. It is about attitude, perspective and experience. A man who transitions to female will never truly be female because he hasn't experienced childhood as a girl, being made to wear ridiculous clothing in certain colours; gone through puberty with all the discomfort that entails. He will never truly experience what it feels like to walk into a public house alone, and feel all the predatory male eyes swivel in to focus on her. He'll never know what it's like to have excruciating menstrual pain, not to mention the disgusting, inconvenient mess.
So, it's no wonder that your female friends make fun of "Transvestites". It is precisely because men like that (and you) think that the female experience is framed by, and limited to, a skirt and a boob tube.

This makes things make sense to me as a person who is a negative target for lesbians as I'm a strictly dress wearing woman who has masculine features and a mustache with middle aged hormone imbalace and shines a light on a behavioural mystery that has been puzzling for quite some time. Thank you for posting this insight.
