He's a black dude who grew up in flint and his father was an alcoholic who was abusive to him and his mom. She practically raised him by herself. He also grew up seeing a lot of kids that look like him in similar single parent households struggle just the same as he. He was also probably reminded of this in the media he consumed growing. He probably told himself that he's not gonna be like his father when he has children and he'll be there for him. Of course a man like that would think father hood is important.
That said him throwing Same sex parents under the bus like that is wack as fuck
Then what he said made even less sense. If he lived this crap with his heterosexual parents family then he would understand that love is the priority when raising children, and not a penis and a vagina as a requisite.
