When a couple gets divorced, they are STILL cousins.
The only recent documented case of incest was between two Leftist California hippies.
Now i have moved out of the area but my high school where my grandparents raised me when they retired there every one that was originally from there was kin somehow. There was 25 in my graduation, but the neighbors across the road got married then divorced and her name never changed and not because she kept her maiden name well she did but it was the same as his seeing as though they were paternal 3rd cousins... i moved back to where my grandpa was originally from i went forward 100 miles and 50 years in a day...
Just like if you check the news, all the overt, outright racist incidents (the ones even we agree are racist) happen in the North and on the West Coast.
