Brian I am somewhat perplexed (and impressed) but I will try and explain. Certainly, different variations of Bob's 'joke' have been circulating incessantly, where you replace the particular ethnic 'target' with one or several of your choice. It is a much used 'anthem' of right wing neo-fascists in the UK and has been for some time. I detest this joke and it's variants with a passion. I did tell Bob privately that I held him in higher esteem and was disappointed by his post.
When I saw it on the board I instinctively reacted the way I did as the deployment of this particular 'joke' has caused real problems in various communities around here. Now, it's no fun being a white person at the best of times

)) but every time that bloody joke circulates we all get tarred with the same brush
again.
I accept that much may be lost in translation in the 5,000 mile journey from here to there.
The Burka/Barka theme is not a joke. It's a serious assault (BY ME) on the symbol of female enslavement in certain communities. It has no Islamic connection save they are made to wear it by their male masters in many households. It is my personal protest medium not an attack on a religion.
The French at least have got some balls, as they have banned women wearing the damned thing.
Finally, as soon as I made the public comment about Bob's joke, I knew I had made an error, but because the admins ignored it and no-one else (except Bob) commented, I let it slide.
Thank you for bringing the matter up so that I have the chance to explain my position on this.
