Actually, across the numerous threads I've read around this, no-one has ever addressed the Rachel Dolezal conundrum.
I.e It is widely accepted that when Dolezal 'identified' as black and lived as and represented black women, it was appropriation, it was inappropriate and that crucially, she wasn't actually black.
The black community who subsequently rejected her as 'one of them' faced no opprobrium whatsoever for doing so.
Why is this different? I don't want trans people to be rejected, but neither do I want us facing opprobrium for discussing it. It has been pointed out that trans racialism isn't a protected characteristic and that transgenderism is, but at the moment, so are women's rights to congregate in penis free environments. That will probably change.
So, what's the difference in intellectual terms between identifying as a different race and identifying as a different sex? Other than the legal position, if we are talking about this being a 'brain' issue and not a biology issue, what's the difference?
