Tribes [and religions?] are too big to confine to homes and no court would agree with your view except in regressive regimes - but this is how the UK is becoming, i.e. a secular nation. All I have been saying is for Britain not to be ashamed of its Christian past, and keep the best bits of Christian culture.
Given that you view this culture as a vile ideology, and that multiculturalist ideology is deeply flawed and has no democratic mandate, what culture should the UK have?
