There are over 6 billion people on Earth. Many of those people are just insane. And television shows have an incentive to bring on the real nuts in order to keep things exciting. As such, the fact that you heard one representative from group X go on TV and say something nutty doesn't allow you to make any inferences about what the median person in group X actually believes.
I think this is not too inconsistent with what the western culture(s) subconsciously believe.
Strange. If western culture "subconsciously believes that marriage is a failed system that should be disposed of", then I don't see why marriage is (1) held in high esteem and (2) heavily subsidized. I mean, when I got married, everyone I knew was delighted and no one told me "this is a terrible idea -- marriage is a failed system". Why would the government give me money once I got married if there was a social consensus that marriage is a failed system?
The problem with asserting things about an entire society's "subconscious beliefs" is that your assertions are impossible to refute. Which suggests that these assertions are meaningless garbage.
