Following your logic, christianity has no place in Europe. Europe will and must remain celtic. And that's not xenophobia.
Those natives peoples were converted not replaced. Your argument is invalid.
Europe reached its peak glory when and because of being Christian.

Peak christianity in Europe actually corresponds to the peak of the Dark Ages. 1000 years of technological regression, religious persecutions, religious wars and no human progress. Name one book or invention made in Europe between 300 and 1300??? Europe would burn "witches" and scientists alike as ordered by the pope.
