A culture which is based on immigration-Romans, Vikings, Saxons, Normans etc. etc. without this we would still be living in mud huts and worshiping witchdoctors, much like the people you know dislike! If you're proud of British history and Culture then you are already embracing multi-culturism and immigration anything other than this and you're deluding yourself. If it's just because your ignorant and scared of foreigners admit it, don't hijack patriotism.
