We surely need to send protest emails and letters to legislators and government representatives – as citizens did in EU for the "chat control" proposals – and organize protest marches, strikes, and so on.

But yes, if the regime behaves more and more like a Russian state, rather than a democracy, and doesn't care about citizens' protests, then "violent uprising" becomes almost a moral imperative. "Democracy" means "government by the people", and it's we people who must make sure no one takes the government out of our hands; nobody else can do that for us.
