The problem in my opinion is that somehow by opening our doors/churches we will teach muslims to love and tolerate. They will turn their backs on us as soon as they can. For many of them, the word of allah is so strong, they would murder over a cartoon, they would murder for family honor etc. They will not return the favour. Trust me. This is not personal hate or anything. People need some serious lived experience in the middle east, or to seriously befriend a muslim family to the point where conversation is open, and you will see how their minds function. The second they don't like something about your way of life, they will turn their backs. I have known many muslims, polite and smart, but put allah above all else. I knew a smart guy who suddenly quit a job at my firm because he was partnered to work with a female and said it is against his faith but our firm wouldn't budge; as he was quitting he suddenly (after 4 years) told us the western world is sick and we are bad people and that he was happy to go to saudi arabia. I knew another muslim guy who was invited to a company holiday party with his wife, he left his wife in another room and said he doesn't believe men should sit with women at a table (to astonished coworkers who sat with their wives). I had a neighbour from middle east who was medical resident and told me many times he couldn't wait to finish his 5 year residency and leave and that he would never bring his wife and daughter to this "filthy world". I questioned him about it once and he said "so my daughter will be raped by a non-muslim?" and "my wife will demand to drive like your wife?" Again, all 100% real stories in north america. Maybe it is my personal experience, but I do not trust muslims. They are nice to your face, use the system for money and education but spit on this soil. They will destroy Europe.
