Not without the English. Without them, no English culture. Without that, no England.
The English language and identity is itself a synthesis and a patch work of different nationalities and tongues. But the Normans showed their worth in battle, by inventing stirrups and breeding big horses. The Saxons were never able to remove them, but their adamant insistence on their own ways of doing things eventually turned into a newly synthesized language. The Scottish Stuarts failed to maintain their monarchy because they lost the crucial battles, but they kept their customs, and to this day the crown prince spends time in the public eye posturing around in a kilt. It’s the respect you give to a vanquished but worthy opponent.
But this Islamic invasion is nothing of the kind. They have proved their worth in street riots with police stymied by ROE set down by politicians. In an honest-to-G-d no-holds-barred battle, they would be sent packing. They don’t deserve to have their culture “celebrated”.
