I don’t think you are grasping just how dire the situation in Europe is.
I am a naturalized American citizen. My hometown in Sweden is now unrecognizable. It was once such a peaceful and charming city. A place that my family called home for over 500 years (that we can trace). No more.
My family has now been displaced from their home because of the crime and violence. Fortunately for my family, we have a lot of property in the north country where the migrants have not yet reached. My elderly parents are safe there but they are now in a very isolated location. This is not how any of us envisioned them living out the rest of their lives. For me it is quite frightening as they are not in the best of health.
You should really take the time to learn about what is happening and why people feel the way that they do.
