Depending on their mood or the point they’re trying to argue against, those symbols can be

• Totally different from Nazi symbols, they’re ancient runes (that are not from Ukraine, but ah well nevertheless)
• Definitely Nazi symbols, but only for the purpose of “trolling” the Russians who lost millions to the Nazis (which includes the Ukrainians lost, but a lot of those were undesirables so ah well nevertheless)
• One or two bad apples, what are they going to do ban using Nazi symbols in their military? (which other western militaries do, but ah well nevertheless)

An excuse I hear a lot lately is that they just use nazi iconography to own Russia so it’s fine

They know absolutely nothing about Ukraine. In particular, they nothing about Ukraine’s long history of using antisemitic violence to protect the rich.
