I would suggest one odd factor in this discussion. As various Muslims left Iraq and Syria....moving into Germany, a very small percentage upon arrival was drawn to read/discuss the Bible. If you take what the news media suggests, there’s probably in the range of a thousand who converted to Christianity. Some might have done it to ensure the visa approval process, but in doing so, they’ve created a lifestyle that prevents them from socializing with most of their former Muslim friends. I met one of them last year in a language class. I certainly won’t go and suggest a large percentage shifted, but it is odd that a smaller group did.
Sorry, I should have asked you to tell me what my experience is.
