I used to live in Russia for a few years and still have many friends and acquaintances there. It totally terrified me that many of them supported the war openly. In fact, my stay in Russia was related to religious organization, Hare Krishna which is quite popular in Russia now, and usually these people are quite apolitical, try to avoid taking strong stance in such matters which could damage their legal status as Russia is not very friendly to new religious organizations. One of their leaders gave a speech which did not name anyone particularly but mentioned that even religious people cannot stay neutral when big transgressions against people are committed. He clearly meant Russian massacres in Ukraine and everybody understood it. Since Soviet times Russians have a skill to talk about pressing matters in indirect way. He was supported by all Ukrainians and totally lambasted by Russians. People who preach renunciation from all mundane matters, loudly objected to their own leader and supported Putin. I was terrified.

I am sure there are a lot of people who simply keep silent because it is dangerous to speak out against the war but there is also a sizable and very active majority who support the war.
