It wasn't the French that got over run, Charles Martel prevented that at Tours, (Hammer of the Moors ).
I think that was the last time France actually managed to defend its self.
It was Spain that was occupied for 400 years.
But those weren't the dirty animals of today.
Those Muslims valued learning and at a time when Christians bragged of never washing (because it had been a pagan ritual) and one of the largest libraries in Europe contained 18 books, the Moors in Cordoba and other cities had hundreds of public baths and books were sold everywhere.
Of course back then most Muslims could read, like the Jews in order to read the Koran.
The change came around the 13th century when the conquerors who were not only warriors, but intelligent men, were replaced by the "politicians", it's been going down hill ever since till now you have a bunch of goat f*cking savages working themselves back into the stone age.
Liberals are taking this country down the same path.
