Look there are racists everywhere, that is a fact. Calling Azov a far right group is a Russian smear attempt.
For Azov the big proof is Andrey Biletsky, look him up. In 2011 he was a far-right pro Russian Ukrainian. That's sorta what far-right means in Ukraine, pro Russian. It also means white supremacist specifically anti-LGBT and antisemitism.
This article doesn't bother to speak on what far-right means in Ukraine or how that stance has been challenged in Ukraine. This article really doesn't say much about anything useful to understand this far-right identity in Ukraine it just uses the term to make liberals pearl clutch.
Ukraine is being invaded if racists wanna pick up a gun and defend it go ahead but the identity of far-right in Ukraine tends to be pretty pro Russian. Meaning a lot of that identity right now is likely in shambles and being challenged.
It is just a disingenuous article. Nothing else to say about it. The entire thing is just "ooh spooky far right Ukraine!"
