I just think it's really patronising when the assumption is made that people who object to their sex being re labelled without their consent just don't understand the problems trans people face.
It's not that we don't understand it's hard to be dysphoric, or even that it's hard to look like one thing and be treated like another.
I'm not saying you don't understand their problems, though I'd still say your understanding might be somewhat limited if you haven't experienced it.
I'm saying you don't understand what it's like to be trans in the purest sense of the word. You do not know what their gender identity feels like. Which, brings us onto this;
men in frocks are men in frocks.
How do you know that they are psychologically men - if you are incapable of knowing?
If somebody says they are not a man because of a psychological understanding they have, I cannot counter that because I simply do not have that understanding of their gender.
Yes I mean stereotypes. The difference between men and women is biology. That is what women are oppressed on the basis of: their female bodies. Nothing else.
Due to gender stereotypes, a lot of misogyny will manifest at gender presentation, not sex. Mainly because you can't really see if someone has a penis or not in polite society.
There's loads of fascinating posts about it: trans women/men either coming to terms with misogynistic comments or actions, of coming to terms with the fact that they Nov longer experience them.
They have put up with being oppressed in this way for thousands of years. And yet are now being told that 'biology doesn't matter' its your 'innate gender identity' that is what is important.
I'd say that 'put up with' is a bit of a downplay, but to focus on your point-
You don't have to ignore sex-based oppression in order to factor in transphobia. Just as you don't have to ignore homophobia in order to factor in racism, or misogyny to talk about classism, but I think people worry about sex and gender based oppression having negative effects on each other because they overlap so often.
But we don't have to ignore one to focus on the other. We have to work on eradicating every type of discrimination. Nobody benefits from petty play-fighting where different oppressed groups try to downplay the struggles of, or discriminate against, each other - except oppressors.
