My local school once had a display about racism in the USA, and it actually covered everything under the sun really well. It had stuff about the racism toward Irish immigrants (particularly in the early 20th century), racially motivated gang violence between blacks and Asians, all the stuff that happened with Native Americans (and continues to happen today)...it was pretty informative! And I was really impressed that they covered all sides of the issue and made it clear that it's about so much more than just the history of slavery in the US. That's important to talk about, too, but it's only one part of a huge issue.

tl;dr, but what I'm trying to say is, yes, I agree.
