The existence of golliwogs in the past is one thing. Whether we should continue to perpetuate these crass caricatures of black people - now that we have 'allowed' them to point out that such caricatures or 'nicknames' are humiliating and hurtful - is quite another.
Calling or comparing a black person to a golliwog is pretty much the same as calling them a wog. I very very very much doubt that anyone would defend that. Carole Thatcher, in defending her abusive expression, now sounds bigoted and stupid.
WRT to golliwogs themselves, I do wish that people who persist in defending these embarrassing instances of past racism would ask themselves why. Why is it so important that we should not have our freedom to be 'accidentally' offensive curbed in any way?
It's similar to people decrying political correctness - do they not understand that there is something far bigger and more important at stake than their 'freedom' to express themselves, uncurtailed by the need to consider the feelings of others?
Actually, strike that - of course they understand what's really at stake, and it is precisely that project which sticks in their craw.
But wrt the OP - Golly/Gosh/bleeding/Crikey/Jeepers afaik are ways of avoiding blashphemy (bloody from 'Christ's Blood' I think)
Some might have originated from the expressions of black slaves but they do not refer to black people or their purported 'characteristics' and so could not, I don't think, be considered offensive.
