Perhaps someone's mind is more important than their physical appearance in defining their identity? Just a thought.
Are you going to come back and answer people's responses to this? Have a discussion perhaps? Or are you one of those tedious posters who drops what they consider to be an enlightened, snappy one-liner and then scuttles off without actually adding anything to the topic?
As per PPs, I'd like to know what you think a 'female mind' is. After all these years, this is often what the discussion boils down to and I've never heard any TRA give a definition that isn't simply a list of harmful, misogynist stereotypes. Some of them know that this is the case, so when asked the question they will disappear and refuse to engage further. I guess you are one of the latter types.
Also, 'identity' refers to a series of facts about an individual. Things like sex, ethnicity, age etc. These are immutable characteristics that are completely unrelated to feelings, thoughts, wishes or desires. Someone may think that they "feel" like a woman, but that feeling has no power to alter their physical reality. Plus, as per my last paragraph, "feeling like a woman" can only be based on misogynistic stereotypes. Womanhood is defined purely by biology, not feelings. If it were based on liking dresses, drinking cocktails and playing with dolls as a child then there are plenty of biological women who wouldn't qualify.
What's the "physical appearance" thing about, too? You don't think that women have to look a certain way, surely? Think you might have shown yourself there.
