You didn't answer my question "what evidence (...) would be needed for you to admit that we don't want to fight, and it's Zelensky's regime (...) that forces us to (...)" :(

Putin is trying to take your homeland and you're doing nothing to prevent it.

What do you mean "take"?
What prevents me from living on the land Putin has taken?
Or let's be more exact - what prevents people in Crimea, Melitopol and other cities/regions taken by Putin to continue living there?
Or maybe you want to say that the life there is worse? Then please define in what way. Is it being able to freely move? Is it not being a subject to mass kidnappings? Is it being able to speak your mother tongue without being discriminated for it (or worse...)? Is it being able to form political parties? Is it being able to vote for your president (even if you consider the elections rigged)?

You're not even in your own country...

I cannot return there, until Zelensky's regime is done. If I go there - I won't be able to come back. I'll be imprisoned like the rest of the country. I'll be sooner or later kidnapped and sent to die.

Who should fight for their freedom if not the people that live there?

Fighting for freedom is fighting against Zelensky's regime, he is the one taking the freedom away. And it's extremely hard to fight him, as long as he has western support.
