Nonsense. Gender and Biological sex should align. The idea that they shouldn't is absurd. Male is Male. Female is Female, with the exception of those rare occasions where there are people born intersex or with some chromosomal genetic situation and a person at that point may need to try and figure some things out. If it's a clear biological male, they need to be for legal, athletic, and for the purposes of public spaces, a male. That doesn't mean if they want to dress up and be a female because they feel that on the inside, they can't do it on their own time. Have at it big guy! And same for females who had rather be a male. Once an adult, go ahead and take all the hormonal stuff you want. sew something on or chop it off, whatever, but you're still whatever your biological sex is.
