@Roz, why not, and who gets to decide we dont like them or their views? Judge not lest etc etc

BTW, I am one of those immigrants mentioned but I damned well won't exclude someone because they dont fit with someone's views. If they are indeed stirring up racial hatred then report them and let the proper authorities deal with them.

Not giving them a platform is denying them a chance to put across their views so that people can judge the validity of their claims themselves.

Life is full of choices, take these away and what do you have?
