When did I pretend to feel offended?
I think you're talking to the wrong person. I grew up in East London during an intense period of accepted racism where open abuse and violent race attacks were the norm. I also routinely work on building sites (when working with office w**kers just gets too much and you need to be around more down to earth people). This environment is also very 'racist' compared to most (although a helluva lot better than it used to be!)
Just so you all know, I have thick skin as a consequence. I could not give an inch of a toss about some 'abusive' words. Water off a duck's ar5e - as they say. Now if someone starts putting hands on people - that's a different matter.
When you spend a lot of time around the culprits, and understand their mentality/IQ - you get to understand that their intellectual limitations pretty much prevent them from acting any different to how they do. They only curtail themselves when threatened physically or with job loss. Other than that - they is what they is. It's a sort of lack of a particular type of mental development. These guys remind me of certain, sniggering idiots I used to go school with.
Raghead is like our equivalent of 'niggah' for blacks. Own it! Plus you're a girl, and that means you live in parallel universe to blokes - so I don't think you'll ever get it.
