LOL, doesn't prove your point at all. Two of them are the "New Family Structures" study which is complete shit. The other one is a single study, which has it's own critcisms. And none of that is emphatic proof of anything. You're really going to hang your hat on early onset depression as the key indicator of proper parentage. Really? If this is all you have, I'd have to say I'm terribly underwhelmed.
