I'm definitely not trying to give the US a pass in any way. I understand that divorce rates in all circles are sky high here, and I think it's because of the emphasis now on personal happiness rather than commitment or community. But that's just me.
The reason I said anything is because the Christian circles I have been in seem to look at the cultural norms in other countries and start advocating that they should be adopted here, because they assume that it will work for all cultures.
For instance, there seemed to be a push for a while for arranged marriages -- at least in the circles I was in.
And some have felt that divorce should be made illegal here as well.
Like anything else, I think there are always pros and cons that need to be approached realistically.
