Sex refers to “the different biological and physiological characteristics of males and females, such as reproductive organs, chromosomes, hormones, etc.”
Gender refers to "the socially constructed characteristics of women and men – such as norms, roles and relationships of and between groups of women and men. It varies from society to society and can be changed.
So people want to be seen as the same gender as they feel they are, this seems reasonable to me.
Also from that same site:
Traditional gender norms are hierarchical: they presuppose an unequal power structure related to gender that disadvantages mostly women.
People don’t think there should be an inherent advantage to being male, which I also think is quite reasonable.
