Racist, hateful maniacs still do.

But Klan delegates defeated the platform plank in a series of floor debates.
To celebrate, tens of thousands of hooded Klansmen rallied in a field in New Jersey, across the river from New York City. This event, known subsequently as the “Klanbake”, was also attended by hundreds of Klan delegates to the convention, who burned crosses, urged violence and intimidation against African Americans and Catholics, and attacked effigies of Smith.
