[Bloody Sam Roberts]

In a few years, are they suitable material for a marraige?

I don't disagree with you but let me ask you this.
Do you believe that no one is cabaple of having thier attitudes towards sex change? This particular girl included?
How can you say with absolute certainty that she will be unsuitable for marriage when the time comes?
How can it be that she will never be worthy of trust? That call is up to her prospective husband...him alone.

In response to your question, the article answers it to a certain degree:

"If they don't date, how will they learn the skills of discernment, empathy and patience that keep a marriage going?"

"A series of fleeting liaisons will not help those traits," Longmore says. "That's why we want them to have dates, so when they get married they'll have them. But if all they're doing is screwing, forget it."
