Well to some extent the Russian citizens are not supporting the war according to the news so why then ban them, the war is political. Not as if Russia is at war with Ukraine but the military who are controlled by the government is involved in the war. I don't believe any civilian Russian citizen has carried arms to support the ongoing war. I may have a different opinion on the call to boycott Russian Businesses unless the one that has a direct connection with the government.
A big confect is there between the Russian people and their government. Their government arrested a number of people because they were protested against their government and wants them to stop the war again Ukrain. therefore we should protest and do boycott against their government and not against their innocents people.
