walden: Why the objection to a 10 year age difference?
Because if you demand that men wait til they're in their 30's to be married, 99% of them will become serial fornicators, which renders them much less likely to ever marry or to have a stable marriage if they do. The few over-30 men who do stay virgins til the wedding, are really messed up by it (speaking from experience.)
Women can wait, if they have to. But men NEEEEED sex and expecting them to wait til they're "old" (and to a hotblooded 18 year old, 30 is "old), is utterly unrealistic.
We've either got to change the system or watch other societies and cultures bury us.
