That's fair enough, and I understand that you're trying to be an even, measured person, and I applaud you for that. When dealing with Nazis and white supremacists, though, we have to understand that their very existence is violence. For anyone with any decency within them, there is no middle ground to reach with a white supremacist. Think about it. What would the middle ground look like?
OK, you can't lynch or kick out all minorities, but we'll let you have half? A third? It's ridiculous to even consider. The only answer is to snuff them out, and it will likely require a great deal of violence. MLK knew it; Malcolm X knew it; and every black person in America with half a pulse knows it.
Remember Ferguson? Remember how the Oath Keepers marched through black neighborhoods with machine guns? Can you imagine if black people marched through white suburbs with machine guns? If you can't, look at why California has strict gun laws - the Black Panthers. Or, why were only a few people arrested in Virginia? And, why were they treated with more decency than people protesting police brutality or the Dakota Pipeline? It's white supremacy in action.
You say you're from a communist country, and you may not be aware of America's history with white supremacy, but it runs deep. People who make false equivocations between groups like BLM and the KKK are no better than the white supremacists themselves, and they're the ones that allow this sort of thing to continue - in 2017 FFS.
This sums it up well:
