I'm sure most Americans also believe that rape and murder are wrong (unless done in some far away desert by the military), yet such acts are featured prominently on Netflix.

Are we really to believe that this [1] is such a horrible act of racism that must be cens... sanitized from history forever?

I think you're misreading that first link. It seems that only 37% of adults think that blackface is never acceptable. That's actually less then the gender one you linked.

Plus that first link is specifically asked about use in a Halloween costume.

I was adding "rarely acceptable" and "never acceptable" to get the sum total of "negative opinions", I think that's reasonable to summarize a poll with many options as yes-or-no. The Halloween thing isn't great, but it's all I could find....

I think that many of the censored episodes would fall under the rare times it is acceptable, though, but I suppose that is just my opinion.
