The quote posted by Maniak doesn't make clear whether it's the result of having no hair in certain places which is considered to be 'gender affirming' or whether it's the actual waxing (by a woman, as a service which is only for women).
If it's the resulting lack of hair, this is clearly not gender affirming, since many women don't wax and some men do, so it's extremely sexist to suggest that this is 'gender affiming' with its implication that it's something all women do or should do.
If it's the 'treated as a woman' which is important, then it's clearly not 'critical' that someone gets 'gender affirming' treatment to help them 'feel like a woman'. Forcing someone to do something which makes them feel uncomfortable and threatened in order to prop up someone else's delusion is not 'critical', it's abuse.
I read somewhere (possibly in one of the earlier threads about this case) that there are a number of unisex waxing salons in the area where JY could have found someone willing to provide the service, but he chose to target these women instead.
