Yeah, the world has gone bonkers. We cannot police what people think. Heavens save us from the thought police! Turning a negative into a positive is the only way. Sure it will still be used against us, but in time the nasties will realise that it no longer hurts, and lets face it, thats all they are trying to do. In response to them chanting "yid" or hissing, our crowd should just chant back "you're calling our name, so you must love us" - in time it will go away. The strange thing is the "n" word. The rappers have got it all wrong - they use it, but if a "honky" uses it, it is suddenly offensive - we dont want that.
There was a very funny play called "The Vagina Monologues" written by Eve Ensler, in which the women identify the crudity and disrespect to women of the "c" word. They embraced the word and started shouting it out until it became part of their identity. There was a very funny episode where the actors picked out a male (one of only a few) in the audience and got him to shout it out - the idea being that it turns a derogatory remark into a positive. Personally, I hate that word, but I am using it as an illustration.
