Personally I don't want to get into a dispute over words like 'vulnerable'. The issue for me is that being vulnerable doesn't mean you can change sex.
I agree flo. It shouldn't be a criterion.
But it's worth addressing, in my opinion. Because it does sway a lot of people.
And I agree with the previous poster that the vulnerability of the original transsexual group is being hijacked by late transitioning men with a fetish.
None of them are women, obviously.
But if people are imagining the former group as the entire cohort, they need to be enlightened.
