Ask the Dutch. Here's one Dutch person's opinion I got from a Financial Times article on the Dutch elections:-

"Ten years ago, I was more trusting — I thought the integration of Muslims would go well here. I did not begrudge anyone his or her existence in our beautiful country. But I now know that for many Muslims, this integration will not happen. As an example, there were big Turkish demonstrations in Rotterdam to protest the [attempted] coup in Turkey [in July]. Demonstrating Turks who have been living for years or were born here, I found frightening. They seem to feel absolutely no affinity with the Netherlands."
