I live in Florida and the northerners who come down are so much more racist than the native born, at least in my personal experience. My ex came from Michigan and went to an all white school up there, never met or hung out with anyone not white. They may not have explicit segregation but do have effective segregation.

So he comes down here where we were forcibly desegregated so I have friends of all sorts and my kids do & also it's just more a block by block version of "segregation" less a side of town so we are just most often in mixed situations and holy shit he was not prepared for that. So racist he held every stereotype you can imagine.

So anyway - I kind of agree, up north it seems they are theoretically not racist but are segregated, down here more explicit trouble because we are together, but it's getting better. Or was at least through the generation following mine, maybe not anymore, not sure.
