I think "Engrish frute" is rather witty, and that taken in context it wasn't racist. (Note to WAV: this is called answering a question. Try it some time.)

Racism is where someone attacks or mocks a person or people from a particular culture or race, which is something I have never done

No, that's attacking or mocking people on racist grounds. I'm glad to hear you've never done that, but that's not by any means the only form of racism.

I could argue that I'm an Italian opera singer by redefining the words in my own special way, but the rest of the world is going to carry on thinking I'm an English folkie. If you don't want me to call you a racist, you'll have to take account of why I call you a racist, not just tell me that you're not a racist by your personal definition. And if you don't want to be considered dishonest, stop bouncing back with the same old slogans and the same old links, and ANSWER THE QUESTIONS THAT PEOPLE ASK YOU.
