I take your points, but two big issues occur to me.

1. There is absolutely no reason for anyone but Christians to look at things from any biblical perspective. And without getting into any major discussion of the Bible's merits, there is a big factor of time/change/evolution involved.

2. It seems altogether way too late for that now anyway - can't solve the problem by shutting the gate after the horse has bolted.

The fact is we do live in a society where sexual activity is considered normal (and indeed healthy) amongst consenting adults. Different societies vary the age at which it is acceptable, or may even not see it as acceptable if pre-marital. But as I see it, those countries bring with them baggage like women being seen as inferior/possessions etc. I don't see any examples where everyone is pretty much free and equal, but pre-marital sex is not the norm.

I can only hope that the current 'shag everyone in sight' mentality will be a cyclical thing. I guess it was big in the 60's too, though in a different way (it was about "free **love**", not 'sex for status' etc). Or perhaps as a species we will even grow past it completely and realize there is more to life than finding someone to have sex with (seems to me to be the obsession of younger men in particular).

We can only wait and see what the future brings.
