They don’t care about the words. They are radical wackos who really are convinced that there are no sexes (they say genders). They really think that there is only one kind of person and that “gender” is a fluid, flexible, changeable thing. They have convinced themselves that a person can easily move from one “gender” to another.
Obvious facts do not convince them.
This “fluid” business stops when you ask about male homosexuals, however. Somehow they’re supposed to be set in stone.
