Nice try; read what is written.
If they’re not willing to commit to each other and the child now, they have no business trying to raise the child.
So it would be ok with you if they got married and divorced right away then? What other qualifications do you require for marriage?
I'm sorry, I've been trying to be kind but you're whole concept of not being able to raise a child because they aren't married is utterly foolish, especially considering the support system Bristol and Levi have around them. I'd be willing to bet you'd advocate the state coming to take away the child and giving it to a 'proper' family, wouldn't you?
