repeating once again, because I have no idea how this is your takeaway if you've read the last few pages in full: the original comment from Phil was that trans people choose to identify as trans - i.e. they are not born trans. if he wants to clarify that statement, then by all means, but he has yet to do so thus far.
it's an important point, because if you are born trans, then transitioning is massively, fundamentally important to that individual for their mental health and wellbeing. as I already said earlier, we should be creating a tolerant environment/society in which trans people can transition safely and easily, not creating even more obstacles to what they already face. What is being proposed is essentially discrimination against trans people because they were born with a misaligned gender identification, and then justifying it as ‘well you chose to transition’. that isn't the actions of a tolerant society.
