As this comment ([1]) demonstrates, I caution you against thinking it's safe to protest in Russia. We are truly privileged to live in a country where dissent doesn't result in being poisoned. Empathy goes a long way towards building a better world.
The ugly reality is that regime change will not happen in Russia without bloodshed, and currently the bloodshed is happening in a country that was unfortunate enough to border Russia.
The war in Ukraine is egregious and refusing to assume the risk as a Russian person is almost akin to saying "better them than us".
