Last I checked, there is no law saying transqueerMuslimplantkins can't identify as transqueerMuslimplantkins. But these are contradictory:
If we remove the attributes of "masculinity" and "femininity", they become something else, or the prior arrangement of traits become something else. In either case, one of the key traits of traditional masculinity and femininity is being binary in nature. Additionally, those other traits you ascribe to each gender are not absolutely dichotomous. The slider is just generally more towards one way or the other. Otherwise you cannot be complementary. Hence binary.
To say that this is harmful, and must change, and then turn around and say "but you should be able to [identify in those ways]" is contradictory. The fact of the matter is you really don't have contradictory beliefs, it's just trying to CYA on problematic beliefs that puts you in an uncomfortable bind.
There is an important difference between tolerating something and supporting it. I'll tolerate the transqueerMuslimplantkins as in I won't seek laws to single them out for punishment. But I am under no ethical duty to offer them support beyond what they may require as human beings. Anything above and beyond that must be at the individual discretion, and if I continue to cut my grass anyway and a congregation of traditional Muslims won't accept the transqueer into a mosque, this isn't an injustice or harmful.
