I agree, BlueBell
But how far does the 'racist' definition extend?
The kind of monkey-chanting that I presume prompted this post is quite clearly racist. No argument.
But if there was to be a law, where would the parameters of racism be drawn? Take in this context, I don't think RosieLeah's question is unreasonable. Would calls of 'white moron' fall within the legal definition. Or calls referring to nationality rather than race, where the distinction can be more blurred depending on the specific nationality on question?
These are just some of the questions that would have to be answered, I presume, if there was to be a law.
However, with or without a law, I agree 100% that matches should be stopped immediately in cases of clearly-racist behaviour such as monkey chanting.
