Political Textbooks?

I found an interesting article describing a recent vote among Texas lawmakers with a ruling in favor of promoting conservative ideals in their schools textbooks and curriculums. I don't want to say here which ideology is right: conservative or liberal; but shouldn't we be teaching students history in an unbiased and apolitical way? Conservative ideals these books will promote include highlights on the NRA and a diminished look at liberal spokesman Thomas Jefferson.
