In response to a darker skinned news camerawoman human having nuts thrown at her at the recent Repiglican convention.
In the past the KKK hung out at the Democratic Party conventions. Now their in-spirit-if-not-in-fact supporters go to the Republican ones. This is what has happened when the American southern Democrats largely switched from the Democratic party to the Republican party.
Also for the Repigs, holding their convention in Tampa probably did allow for more southern-style racists to show up.
Everyone's a bit racist, and we are all animals, but we're also all human.
