Then again, it could have been one of these instances where someone makes an ironic / subversive suggestion and no-one spots it. e.g. There is a factoid, I think Harlan Ellison [who as we know is reliable source for this sort of thing] says in 'The Glass Teat' or 'The Other Glass Teat', that when 'the network' decided that 'The Mod Squad' should have a more mainstream character added to appeal to Middle America, the writers called the character Christian White and this was only spotted and changed at the last minute.
