For the racist right, a ‘national divorce’ is about racism and bigotry – to create a ‘new country’ where people of color constitute a tiny minority, and where people of color would be subject to all manner of racist, neo-segregationist policies.
The right’s effort to destroy America through ‘secession’ is fundamentally racist – the desire of the racist right to get away from ‘the blacks’ and ‘brown people’; to create a country that’s overwhelmingly white.
