>> The studies of grandparents ... raising children — it damages the child...
Not to dismiss your 2-Parent point, but the generality of “the studies” is BS. And you’d admire those I’m defending against “the studies.”
I could have worded that better. The general point is that mother/father homes are the place where children do best (regardless of income). Everything else produces varying degrees of lesser outcomes. I have no idea what your last sentence is saying.
