Is it any worse than the anecdotes about the guys beating their wife and kids? It is a bit offensive, but on the other hand, if we are being honest real life often is. I do not think we should go out of our way to offend people, but neither should we go out of our way to be offended.
I have never met someone in real life who would say that sexual promiscuity is worse than beating your wife and/or kids. Your moral compass is indeed in need of calibration.
