Cousins
So... the cousin thing is pretty American. In the UK cousins marry all the time. It's not a big deal. But in the US it's a taboo to marry a cousin.
I'm not saying where we should go with this, but in the UK marrying a cousin is a rare but mundane thing.
In the US marrying a cousin is, in certain States, illegal. And in other States it is not illegal but a comedy staple.
I just thought it was funny that the show would go down this route. It's like they thought they had a shot at America. Hey, maybe, but this won't shove it over anybody's edge.
All that US comedy talking about cousins? Weird, irrelevant and anti-science.
In an ideal world people would pick partners based on a bunch of silly factors. There's a natural reaction to reject close relatives. But there's actually also a strong human reaction to embrace close relatives who match your genetic markers.
Humping a pile of bones that used to be your grandmother, is icky. Humping your Uncle's kid, not so much.
I appreciate that the UK may be a unique example of this. It's a small country with a hugely marginalized population.
If you have an opinion on this I'd appreciate that you cite your scientific basis for it, otherwise you just sound shouty and weird.
