I do hate these days of supposed political correctness. If anything, what it is doing is trying to discriminate against actual beliefs in general. But, I'm not going to get into idealistics of politics, since that's not the topic.
Comedy Central seems to do a "secret stash" on Sunday mornings at 1AM ET, where they show unedited versions of movies, and put a disclaimer before going back to air that this is going on and parental discretion is advised. Couldn't they do something similar with the Black & White Overnight's, especially since the show is being done at 3AM ET?
If that isn't going to suffice, then how bout getting out the picture scrambling machine? Wherever it says Winston or Salem or such, just scramble the picture over it. Then, if they say Winston or Salem or such, get out the bleeper. Unless of course that would mean totally changing the tapes. I wouldn't want that to happen, since black and white television is always a work of art, and not just something dumb to fool with.
