Not a big fan of people described in the OP, yet I won't throw stones. Why? Because those who's sin of choice is sexual in nature may need the structure this type of courting offers. It would be like making fun of a 12 stepping recovering addict or drunk for going to meeting. Sure I don't have to goto meeting to not drink or do drugs, but not everyone can say that. Like wise not everyone has the were with all to date responsibly, and may need structure and clear headed thought from a outside third party that I myself do not need.
Who am I to point out another's weekness?
