How related is too related?

Might be a little too close for me if she was a second cousin. But wouldn't ever judge someone else marrying their second
cousin. Saw in Idaho they can marry their first cousin or it might of been Utah which makes even more sense, that is a bit
weird to me. But still, not going to judge. I just have seen some people marry their first cousins and the kids were really
slow and that would be a terrible thing to witness. Understand your son shutting that down even if she was a 2nd.
