Owen the Ochlophobist has a really good post on Plastic memories that is definitely worth reading. He writes:

So often the discussion of the drastic changes in the human psyche and human social order seen in late modernity are framed in language of the supposed culture wars, etc., but I think much of this misses the point – as if “correcting” divorce, abortion, homosexuality, etc., can happen or is fundamentally meaningful in a culture which throws everything away. …

I was intending to post my own thoughts on related matters as a prelude to recommending his post, but have just deleted them, and really need to stop. And in any case, Owen expresses these things far better than I do and what I did want to say was still half-formed.
