It's a very small fraction of Ukraine's overall fighting force. I certainly don't approve of nazism, nor do I approve of fascism, hate, bigotry, and intolerance, in any other form it takes.
Right now it's Russia that is committing genocide, not the Azov battalion, so I'm okay with focusing on that as the primary problem.
At the end of this all, if any of the Azov or other neo-nazis are still alive, then I'd push for denouncement and renunciation of them.
