I was listening to some of the arguments in front of the supreme court and one of the advocates of the DoMA said that the primary function of marriage is for reproduction.
One of the justices said they disagreed because people often get remarried late in life 60+ after a divorce or a lose of a spouse and can't reproduce. Legislature that was based on that idea would limit their rights.
He then said there's always a chance of conception, after which the justices laughed at him.
This almost seems like a trend, rather than just a few people. It seems every other week some social conservative says something that makes it seem like they know less about sex than a 10 year old, i.e. women can't get pregnant through rape for example.
So is there a general trend among social conservatives to know less about sex than everybody else?
