It's the word "gollywog" that is offensive because it has been used as a term of racial abuse. You've also gotta admit the toy itself is a bit of a stereotype. A bit too close to the "blacking up" that the black and white minstrels used to do.
Language is important because it structures thought and also lays down indicators about what is acceptable in society.
I'm not sure there are such clear markers about what your apparently condoning and racial abuse either.
I accept your point about gollywogs, but isn't the suggested removal of the word "black" from a nursery rhyme taking things a little too far? Unlike gollywogs, black sheep do exist, and so the only reason I can see why anyone should object to it is because the expression "black sheep" refers to somebody who is an outcast, so given that interpretation, it could be seen as insulting.
Religion should not be taught in schools, it should be up to parents to teach their religious beliefs to their children. In some parts of Scotland this has caused a lot of Bigotry. When new schools were being built two entrances to the building had to be built, one for Catholics and one for Protestants I could not believe it what a waste of money. No wonder there are still problems concerning religion. It is time for this to stop. All orange walks and catholic walks should be stopped they are like red rags to a bull and cause nothing but trouble.
Religion has caused nothing but trouble and educators should have nothing to do with it. It is the parents who should take care of religious teaching.
This was at the instigation of the Catholic Church in Scotland - the same church which also tried (unsuccessfully as far as I know) to insist that Catholic teaching staff and pupils should have separate toilets, cloakrooms and eating facilities from the other staff and pupils, whether Protestants or of other faiths. Of course this largely applied to the Glasgow area and its surrounds where religious bigotry is still alive and kicking.
Last December the Scottish government passed a Bill making sectarianism in football a punishable offence, so maybe it's time they also looked at sectarianism in schools because it's at this level that the fire of religious bigotry, which often starts in the home, is likely to be further fuelled. And, yes - it's high time that Catholic and Orange parades anywhere in Scotland were also declared illegal.
