Yes. Benefits ARE withheld from a live in girlfriend. I am not aware of anyone trying to get benefits for someone on the basis that they've had premarital sex with them. Where did I miss this?
Do I think someone should have the right to withhold benefits from people who openly engage in behavior that morally offends them? Yes. That does not mean I believe they should do so in any particular much less every case.
