Again another insipid post from a citizen of a has been European (failed) state.
Your ancestors threw out Churchill after the war, immediacy. How f-ing stupid are the British people?
There is no evidence at all that any such thing will happen. The demographic collapse in birthrate has many factors but competition from foreign imports is certainly not one of them. In fact, Mexico's birthrate is dropping even faster than the US rate.
Why do you feel the need for ad hominem attacks? It doesnt add to this discussion. As a side note though, the British people did not throw out Churchill. They threw out the Conservative party, principally because it was out of touch with the electorate. Churchill himself remained very popular.
