It is usually an error to waste one's time on things that have no relevance to the real world. We should, therefore, ask ourselves: what difference to Russian aggression would be made by a few self-indulgent people "cancelling" Russian culture? In other words, as Russian culture remains regardless of what self-indulgent people choose to do, and as Putin will continue to fund war crimes in Ukraine until all Russian forces are exterminated by real-world means, silly babble about "cancelling" Russian culture is not merely irrelevant - it's profoundly stupid. Anyone who cares about Ukraine should be sending money, pressuring politicians to find a spine and stop dithering over involving NATO directly, or going to help in practical ways in Ukraine itself. Silly childish nonsense about "cancelling" is not merely a total waste of time but deeply insulting to people suffering real-world harms at the hands of the Russian barbarians and criminals.
