Peoples lives will not be risked by a bloke going home from base and buggering another bloke. Moral, order and discipline will still be in place, and people won't have to worry about good soldiers being discharged for off-base behaviour that doesn't affect their service.These regulations are in place, to keep good order among the ranks, for the good of the service. Not to discriminate against anyone.
Good order, morale and discipline take priority over political correctness. People's lives are at stake.
