Because Americans are so good at distinguishing Slavic languages by ear in a noisy room?
I live near a Russian Orthodox church. People complain about the congregants, but mostly about their parking. A house opposite the church as a Ukrainian flag prominently hung; on the other hand one of the congregants has a sticker of the Ukrainian flag with the don't-tread-on-me rattlesnake. I don't think most Americans care enough to be rude to Russians.
We visited St. Petersburg some years ago, probably 2012. I very much enjoyed the visit. Everyone seemed to be much too preoccupied to give a damn where we came from. The cases of Griner, Gershkovich, and the NCO in Vladivostok do make one wonder about the prospects of American tourists.
