I'll start with the pushback. I'm a huge critic of my own country (USA) but that's one thing I think we get really right, and that many other countries get really wrong. I don't care what the "ethnicity" of my neighbors is. I don't give someone a blood test before I decide to be friends with them, or to welcome them into my family. This whole "I am the pure German, and you are only living here!" ethnic purity attitude is so gross and really not something I can even remotely relate to.
