Me and the wife don't watch it for that reason, we are christians and we watch some heavy shows but that's always the line in the sand.
Interesting story, take it for what it is: Friends of ours always rave about it, and since they started watching "together"... marriage down hill... neither one wants to admit it, she is upset be cause he is all fixated, he is thinking its an excuse to watch whatever now. All in the name of open mindedness. I recently had to talk him out of a fantasy of owning a strip club (at his wife's request). It's a mess.
Like the OP I think otherwise its a great show concept, I'm not protesting it, no nor am I judging anyone for doing so, you reap what you sow is all.
