Errr... I didn't do that, and I was agreeing with you. Sarcasm. I was tweaking the 'I think I'm holier than thou, but I'm really not holier than a cheese sandwich' posters.
Oh, okay, I somehow missed the /sarcasm tag.
Actually, I think conservatives might get a little more traction on moral issues if they didn't come across as painting a version of the past that never quite existed. Though illegitimacy rates have skyrocketed in my lifetime, the existence of premarital sex is nothing new. What's changed is the consequences.
By my understanding, it used to be that if an unmarried girl got pregnant, one of two things would happen:
BTW, another thing about the above consequences is that they represent the 'natural' consequences of people's actions; if anything, society is making them less severe than they otherwise would be. By contrast, those who would throw in jail unmarried couples who share a roof (whether or not they share a bed) are seeking to impose artificial consequences for the people's actions. For whatever reason, people tend to respond better to "natural" consequences than artificial ones, probably because in the latter case they blame whoever imposes the consequences while in the former case they have nobody to blame but themselves.
