Is the point you keep referring to that what Canada and Australia are doing isn't tyranny and oppression? I'm unsure because you gave no reasoning for that beyond your say so.
The analogy you tried to draw with speed limits and water additives has been shot down.
The only things left are that Putin is oppressive and tyrannical, and dog crap. What Putin is doing in Ukraine is neither of those things, it's war, or barbarism. If he didn't have half the nukes in the world he would be tried for war crimes. If you were referring to him locking up the Russians who are protesting his actions, much like Canada and Australia have done, then I agree. I wonder if he seized their financial assets too. That would be real tyranny. Like Canada.
