Ben Shapiro:

Social liberalism seeks to promote a "live and let live" society wherein all types of deviant behavior is tolerated and accepted. Those on the left have thrust their notion of a "civilized," amoral society upon all of us. The fact of the matter is that "live and let live" directly contradicts the notion of communal society; we all have to abide by certain rules to live together. An amoral society minimizes the rules under which we live together; any change in those rules is bound to affect all of us.

And it has. By discarding traditional morality in favor of amoralism, we have catered to the lowest common denominator.

We have successfully defined deviancy down; the deviant is now considered normal. Meanwhile, we have defined deviancy up; the normal is now considered deviant. And the effects upon my generation -- the porn generation -- have been disastrous. We are apathetic about morality, and that apathy translates into nihilism and narcissism -- and in the end, into generational self-destruction. Like it or not, the porn generation is the future of this country.
