Answer me that one; why is it the girls that have to give up their lofty ideals that are based in holiness because not all boys are that way but the boys, whose ideals are based on gashmius, are not told to be realistic because not all girls are like that. Never mind because they are wrong ideals.
It’s a sad reality, but the cold, hard truth (b’derech hateva) is that it’s because of supply and demand.
