It's disgusting and a sin
Why don't you have sex with animals too since something like that is so "normal"

I just don't understand it. There are so many potential partners and you choose to pair with one which is related to you by blood? I just can't believe anyone would really do that.
Also if they have a child it'll likely be handicapped.

That's a little too Koons for me.

How is it a sin when in the very Christian deep southern US incest is so popular?

But anyway, it's just bad. Kids who are born from incests usually have bad diseases.

It's their prerogative, certainly doesnt affect me so who am i to judge

Cousin roll up the partition please

What can I say, my brother's in good shape.

Exactly why you think so many people in the south got so many disabled kids rolling around.
God is punishing them.
