A little bit about civilization. Modern society in Russia is extremely interesting. For example, I grew up in a part of the country where the Christian religion dominates. At the same time we have shared Church cemetery with the Jews. I have never seen such a thing in Europe. There are Jewish cemeteries (of Jews) and there are Christian cemeteries. They never bury non-Believers on the territory of the temple.
Given our modernity, it is not surprising. Only cemeteries of the 19th century. I can't talk about the 17th and 18th centuries. There are no graves of non-aristocrats left. They were buried in the family crypts. However, the joint graves of the 19th century, where Jews under the star of David and Christians under the cross lie side by side. This was unthinkable in "civilized" Europe in the 19th century. If only in revolutionary France, and then I doubt it. In secular cemeteries, it's easy. It is not possible to visit religious sites at the temple.
The second moment from the present. One of my best friends in the army was a Muslim. We communicate even after the service. We have mutual respect. And I grew up in a Christian part of the country, and he grew up in a Muslim part. I am an atheist and he is a Muslim.
It wouldn't make any difference to me. If you do not observe what problems in Europe. When she was faced with migrants from Muslims. We have no such problems. Religion or nationality is not important. It is important what kind of person.
Given that we had the USSR and there is still some inertia. We don't care about the following things:

1. Education
2. Economic situation
3. Religion
4. nationality
   It is important who the person is. It is by his personal characteristics that you will either be friends or rivals. For example, a Korean was sitting at the same desk with me. He is generally a supporter of Zen Buddhism.
   This did not entertain us until the Internet was available. When the Internet appeared, we were surprised. People betray this value, how much money you have, nationality, religion. What's the difference?
