That's a much bigger ask than you seem to realize. Overthrowing a dictator is an incredibly bloody undertaking. Even if you win, there's no guarantee that whoever takes control of the country will be any better.
Doesn’t have to be. We did it in Portugal some 50 years ago [1]! I think just four people died.. We have been living in democracy since then, joined the European Union, etc.. So, it is possible..
This is why only four people have died. Death toll in Russia in case of a mass revolution would be tens of thousands, if not hundreds of thousands.
This is exactly why I'm doing what I can, but avoiding any violence. This is not the way we win this.
