Polite Paradise

I feel like ignoring problematic attitudes, even in the past, is dangerous. I'd much rather us be able to have conversations about the issues than pretend they didn't happen.

What are they going to do with Huckleberry Finn?

This.  I'm going to encourage my daughter to read LIW's books, Huck Finn, and such once she's old enough to do so.  Then, when she asks why they talk about people that way, I'll use it as an opportunity to teach her that people used to think that those sorts of ideas and ways or relating to "other" people were okay, but now we know that those things aren't okay.

That way, she can learn that it's okay to change the way we think about things when new information or knowledge is available.  That's a concept that I think far too many people don't get.
