I have to say racism is the epitome of low and brainless.
Unfortunately it goes both ways though I have been on the receiving end. I was working in a largely ethnic minority area when I was told in no uncertain terms by three rather large lads that white trash like me should get out before I got seriously hurt as I wasn't welcome! That was when I went into a shop to buy a drink (not by the shop keeper I hasten to add). To be threatened or abused because of the colour of your skin is frankly sickening on any level!
I love cooking Indian food and always buy my spices etc. from Indian and Pakistani shops in the Gladstone area of Peterborough, indeed, I was there on Friday to replenish my stocks. I remember a few years ago, as I came out of a shop run by a very nice Indian family, whose daughter I actually taught French to in the late 90s, an oldish white woman shouted at me from across the road calling me a 'white trash Pakistani (she used the diminutive form) lover' for having gone into their shop! When I enquired as to why she should say such an appalling thing, she gave me a tirade of abuse that, quite frankly, shocked me. I told her that no matter what she said or thought, I would continue to support this particular shop and that she was a nasty old bigot! More abuse followed...
