I don't think the tolerance of intolerance is the way.
That's a nice infographic and all, but we're not talking about that level of tolerance. Tolerance of a website that has some words and pictures on it, or tolerating someone saying something you disagree with on a college campus, is a lot different than tolerance of Germany invading Poland. We have laws against violence, harassment, and even defaming in some areas that cover when these things go past just talk. At that point everyone is onboard with enforcement because it's gone too far.
I really think BLM supporters, for example, fear this white-supremacy propaganda because it's so similar to their own tactics and agenda. Their goal is to sweep across the country by taking hold of the narrative, so they think this garbage has the potential to sweep the country too. But the average person is at work and paying bills, trying to live a peaceful life, and sees all this stupidity for what it is.
