Looking at your problems from afar, I would suggest that about 1000 Christian Brits emigrate to India or the Punjab, and then start protesting that you do not have enough British customs in the country, and see how far you get.
You get people like that in most Western democracies, not just the UK. So moving abroad, unless you want to move to a third world dictatorship, isn't the answer.
Moronic individuals like those pictured need to be dealt how anyone inciting hate crimes should be, but they make me no more likely to support the BNP than far right racist rallies make want to become a Muslim. I'd like to think most people can easily tell these bunch of wankers (beheadings for God sake... ) are simply that, and that 99% of Muslims find them equally deplorable.
