Thank goodness they don't. But we accept it anyway.
Television programs and the media portray living-together and pre-marital sex as "the norm." No one questions it.
There are no calls to ban the sermons against adultery and fornication because they are "hate speech."
What sermons? I have yet to attend a Christian service that condemns sexual sin of any kind. (Perhaps they don't want to be insensitive to the adulterers and fornicators in the congregation.)
Today's churches are more likely to speak out against the "evils" of big business or not caring for the environment, than suggest that their parishioners are in any way responsible for their own behaviour.
If some of them would take a stand (against sexual immorality), perhaps we wouldn't be in the mess we are in today.
