Could all players and fans at the @FIFAWorldCup please remember that Russia is currently invading Ukraine and therefore it isn't polite to express support for Ukraine. It hurts Russians' feelings.
Take some basic etiquette lessons. In Russian if you say "в Украину" to mean "to Ukraine" it hurts their feelings because they don't consider Ukraine to be a country. Say "на Украину" to indicate that you think Ukraine is just a territory on the edge of Russia.
In Russia, don't say that Russia invaded Ukraine. Say that volunteers from Russia have gone to Ukraine to save the Russian-speaking population from a fascist genocide.
It's customary in Russia to refer to the Ukrainian government as the "junta" and to Ukrainians as "banderites".
Remember, Crimeans freely and democratically "joined" Russia - they weren't "annexed".
If you don't want to talk about Putin shooting down #MH17, just say "no one can ever really know what happened".
Finally, remember that places where people speak Russian are basically part of Russia.
