It doesn't matter what country you are in you respect the laws/rules native to that country. This kind of thing will not only incite racial hatred, its bound to start a riot.

In fairness if you don't like a country sod off. If I went to a country that said you need to cover up thats fine. If you go into a church you take off your hat, you go into a synagogue (sp?) you put a cap on, if you go into a mosque you take off your shoes.

If you are in the UK, you must be aware that it is an historically christian country, with Christmas and Easter. People that don't like it, the way people dress what they believe etc should either shut up and put up or leave. simples.
