What if men visited and claimed they were women - would they be warmly received?
Askin’ for a friend...
Men as women - we have had this phenomenon with us down through all civilization, and probably in even some pre-civilization tribal societies.
This “gender-bender” anomaly has been a continuing thorn in the side of morality and justice in varying degrees, and currently we have a somewhat more intense exposure to this form of twisted thinking, but the chromosome count is still the determining factor. The function of gender is supposed to be for purposes of reproduction and propagation of the species, as cloning is not yet a fully perfected technique, and has its own limitations even when successful.
The male and female characteristics CAN be stripped away, but what is left is essentially a neuter, unable to reproduce and with none of the specialized strengths of either male or female.
Either you is, or you ain’t.
