Everyone has the right to know!

Countries should not leave out pieces of their history out, even if it is negative. The country's citizens have the right to know about their history, whether it is a good thing or a bad thing. I think everyone should be able to know about the negatives in their history also so that they can try and not commit the same mistakes their ancestors did in the past. History is the past and you cant really change anything about it, so you cant lie and leave the things you do not feel proud about out of your textbooks. Everyone has the right to know about them.
