You are quite right, Britain is a nation of immigrants, however, those immigrants were from the same European continent, they all shared the same common ancestry, history, lineage, and practises that other European nations do. Those immigrants shared common ancestry with us, but peoples from the indian continent clearly do not share common bonds with us, and neither do we with them. If we were talking here about India become a minority country due to the indian white population, people would be calling it genocide. We are facing no different here.

Of course multi-cultural Britain is here to stay in some form, but do we really need to be a minority land, i.e where our own people are a minority, to prove our 'Politically-Correct' principles?
