If you pick up the current issue of North & South magazine, you'll notice the unseemly spectacle of the editor, Keith Poulter, mocking his readers (see the editorial featuring Bigfoot). "Mocking" is too sedate a word - he's in a Usenet-style flame war with the people who pay his bills.
Those who believe in "black Confederates" have made a case. Their evidence is either adequate or not. If not, it is enough to say why.
