Why would you stop Islam? Would you vote for groups like BNP to defeat them?
It promotes intolerance, bigotry, extremism, and undermines the Christian values of the UK. Moderate muslims in small numbers I have no issue with, but how can you tell? It's nigh impossible.
Until a genuine conservative party comes along (not the left wing Torys masquerading as such) I will continue to vote UKIP.
