I'm probably going to get mega canceled here but I think a good portion of it is that the Holocaust is history.

A lot of what we don't talk about is how we treated the Native Americans because we're STILL shitting on them from on high. For example, the Dakota Access Pipeline is the same old shit, different century.

Also talking about how we've treated people of color, and any discussion around chattel slavery, ends up being "uncomfortable" because an awful lot of people in this country don't seem to see any problem with it and would be perfectly happy if we could toss out the civil rights acts and go back to having separate water fountains.

TLDR: it's 'history' in Germany because ya'll arrest people giving nazi salutes, but in the US wearing a KKK robe is "free speech".
