"Today's Americans accept behavior that our parents and grandparents never would have accepted."
That's because it has become so vile to tell somebody their behavior is unacceptable. Remember, the lib goal is to insure that no behavior is unacceptable that way whatever their personal derelictions are they can maintain them under the guise of protecting all. Standards are similarly frowned upon because they necessarily mean others have to live up to them, and that's not fair. Especially if the "others" are themselves! In short, libs are morally bankrupt, like it that way, and strive to maintain carte blanche access to perversion.
