I've said this many a time, and it can be difficult to come to terms with.
Islam and the peoples from Africa and the Middle East are the evolution of humanity in future Europe. They are what humans, and throughout the Animal Kingdom, do to dominate an area and ensure future generations. The Islamists, and other immigrants settle in large numbers, have large numbers of children, take over areas, and eventually, due to sheer numbers, establish political dominance. Once established, the native population contract in size, either by emigrating or simply dying off.
The native Europeans have thrown away their history and culture for large-scale immigration that was only supposed to be a temporary fix to post WW2 economic woes. Well below birth replacement rates, feminism, the rise of large-scale acceptance of a homosexual lifestyle, the shunning of children and subsequent self-interest, and other liberal causes have only assisted in the eventual fall of Europe. I am not arguing that any of the above is morally correct or not, but I will say that even if morally just, they will fall to the religion of Islam and its adherents.
The European Liberal will find himself swinging from a noose from the sour apple tree, over the bones of a fallen European soldier, at the mercy of the new Islamic conqueror.
In less than two generations, Europe as we know it today is doomed.
