Would you let another guy to paint your fence if that other guy just happened to rent a flat from the torturer and having no means to move out? Because that's the correct analogy, if you just cancel Russian that can't affect government in any significant way and stand against war (and de-facto most likely go to the prison if they are brave enough to just mention that).
Or how do you feel about being canceled out yourself because you live next to the torturer and not preventing him from torturing your neighbours at your own expense?
