I'm guessing that this is, in part, an implicit way to suppress hypergamy by leftoids who know it's an issue but obviously can't just come out and say it. People will figure out ways to rationalize solutions to problems that they're not allowed to explicitly acknowledge.
Along the same lines many leftoids probably subconsciously know that their ideology provides a clear path for legitimizing pedophilia, so they have to overcompensate.
