Having morals and rules once meant that most people, even those with raging hormones, refrained from bed hopping/hooking up/having sex until they were married, or at least until they were engaged.
Most people did NOT move in with someone else, just because they were "dating" and before the Flood, when I was in college, no males, except one's father, was allowed in a girl's room, to help with moving in or out at the beginning or end of the school year.
Now there appears to be NO rules at all and THIS is the result of that.
Thank you, feminism.
