The guy made a fair point at the start by saying that he doesn't define himself by the arbitrary borders imposed by an island and statehood, but then he seems to contradict that by trying to control people through the arbitrary borders imposed by his man made faith.

It then got very, very rude with the going around the streets telling people what to do aspect. I am just paraphrasing, but something along the lines of 'Do not dress like that in a Muslim area!'. But you said before you don't believe in arbitrary borders and here you are defining geographic areas! It is aggressive, rude and how dare someone tell another person what to do with their dress sense. You are wearing a dress! I really believe most migrants are decent people and want to just fit in. However, for sure as has been pointed out elsewhere, there are some very peculiar people and they are quite Nazi in their thinking.
