The increase in Nazi propaganda being distributed in America is a blatant reminder that bigots and racists continue to fester and plot, seeking any opportunity to spread their hatred.

Which is a problem. As BHM said, it resides in the hearts of men. Difficult to change that.

But the systemic racism, and/or legacy racism that affected peoples' lives and put them and their descendants where they are today, that we can change more easily. And we've made great strides. In some ways, it may be a good thing that a lot of people now say "what racism?", because we have come so far that it isn't always obvious anymore. We need to point out "that racism right there" when asked that question, and then tackle that issue.

I was a Boy Scout. In adulthood I made the connection to the Hitler youth. At the time, even though I was interested in WWII even at that age, it was mostly the battles. Not the politics. So I didn't make the connection. I got more into the politics in my mid-late teens, and was out of the Scouts by then. To be fair, what stuck with me was appreciating the outdoors, doing "good turns" (i.e. be nice to people), and a few things like that. But maybe that was just me.

A quick check...they have declined a lot. They had 4M youth in 1973 (when the population was a lot smaller). They have 700K+ today with a much more populous country. Basically, it's dying. COVID hit them hard, and they aren't recovering.
