I love the story. It was really an interesting read. Who would have thought such laws and measures could exists to keep masculinity in check. The idea of a correctional facility situated in some far away location are all part the beauty. Perhaps, Marcus will indeed be back as a changed person.
But....
It wasn't a termination facility, so I don't get the part where you mention a drastic fall in the population of males on earth. Are they not allowed to return home? Not even after the so called "correctional facility".

Well done @mgaft1.
