You're intentionally missing the point. The question isn't if there are nazis in Ukraine, the question is how powerful they are and if their influence on Ukraine's government is significant enough to justify Russia's actions, or to make Russia the morally superior side in this conflict.
Additionally, it is intellectually dishonest to ignore that swastikas and far-right symbols used by Ukrainians need to be viewed against the backdrop of Ukraine's specific history - a history in which they were subjugated and genocided by the Soviets, so that the nationalist half of their population viewed the invading nazi forces which fought against the Soviets as liberators and sided with them. In the Ukrainian context, these symbols can also signal an ultra-nationalist or anti-Russian attitude and don't necessarily have to mean the usual "gas the jews; let's exterminate all non-Aryans" drivel.
Well the answer to 'how powerful the Nazis in Ukraine are', is that they are the single most powerful group to exist once the government propped up by the west falls. They have the established politicians, the weapons, the numbers. They led the revolution and fought the front lines of the battle. The ultranationalists taking power when/if we abandon Ukraine is as inevitable as the Taliban and ISIS were.
Also its absurdly intellectually dishonest to make excuses for literal swastikas, SS tattoos, black suns and more by people who passed out copies of The Protocols of the Elders of Zion and Mein Kampf at their insurrection. Their politicians gave speeches declaring world jewry the enemy, they see themselves as a direct continuation of the grandfathers who massacred the jews in WW2 and when Azov got flown around europe for training in the west, they took selfies posing at Auschwitz with Hitler quotes on their clothes.
Right now today most shrill harpies of the democrat party would waste not a second to label you a Nazi if you said marriage is a sacred institution between a man and a woman. Like Obama did. But the guys who paint swastikas on their trucks, commit war crimes and worship adolf hitler? The guys who handed molotov cocktails to 12 year olds to fight the Russians 3 years ago? They need excuses? They need context? They need 'intellectual framing'?
Goomshill to this day still controversially declares that Nazis are bad and we should oppose them.
