You're welcome, Katherine and yes there is -- which is why all this book-banning and AP course cancelling ticks me off so much! Kids have ALREADY missed out on learning so many things about people different than themselves and now it seems, they don't want them to ever know! Just crazy. You should keep following "the Professor." I call him that because he's an absolute font of information! Old as I am, I'm STILL learning so much from his posts.
