I'm pretty much comfortable with anything that goes on between consenting adults, in terms of stroop-age or anything else.
If an individual feels that they are the wrong gender and wants to transition to a different gender, and they've undergone their requisite psychological evaluation, counselling, whatever, knock yourself out.
In the fu cked up world in which we are all currently residing, it strikes me there's so much more worthy of our collective ire than these relatively minor things.
Or a meringue?
