You don't like/hate me questioning immigration and encouraging more English culture in England, so you keep trying to brand me as a "racist".

The point is (as I know I've said before) that you're questioning immigration on racist grounds. You believe that having multiple cultures in one state is a bad thing (so foreign people shouldn't come to England and maintain their own culture) and that for people to lose their culture is a bad thing (so foreign people shouldn't come to England and assimilate). You believe that different cultures, ethnicities, races should be kept separate - regardless of what the human beings involved might want to do. That is racism.
