Replace russian with jews and think about how your comment sounds again.

Of course it's not like all russians are against this war, both because of propaganda and the imperialism in the culture (though again that's very perpetuated by propaganda). That doesn't mean all of them support it, the numbers are also definitely not actually 80%, and even if they were 80% i can't put into words how fucked up it is to discriminate against the other 20%, almost 30 million people, just because you perceive the majority as being bad.
