...or was even worse than today and was quietly accepted.
I don't know what world you lived in, MAC, but the idea that morality was "worse" in the 1950's and early 60's and "quietly accepted" is a remarkable stretch from the reality of American life 60 years ago. (Sounds kinda like a Hollywood revisionist perspective to me).
As much as I may regret it, I'm going to continue with another question for you....
Have you ever been to a country with either no traffic laws, or unenforced traffic laws? (like, say, India where people drive on the wrong side of the road at full speed because they feel like it??)
Is traffic the same as, or better there than it is in, let's say, America, where traffic laws are stricter?
The truth is, that when society agrees upon and enforces standards, behavior overall is BETTER. That is not to say that in America no one speeds or runs stoplights, or even drives drunk, but to say that a country with legal and societal standards makes behavior WORSE, is nearly an absurdity.
When American culture expected sexual standards to be upheld, many, many people avoided bad behavior because of the shame of a society that, as a whole, agreed on those standards. That is not to say that adultery didn't exist, that sexual abuse of children didn't exist, that children engaging in oral sex didn't exist, that illegitimate births never happened, that rampant promiscuity in some individuals didn't exist, but to say that American sexual morality was WORSE in the 1950's than it is now, when many people think that absolutely nothing is wrong if you 'feel like it', is, frankly, ludicrous.
