America is bias

Countries should leave all of their history, positive and negative, in their textbooks, because the people have a right to know about their country's history and past. You can't just leave out something that makes you look bad, and deprive the people of the truth. They should embrace the good and bad, because it ultimately shapes out country into what is is today, You can't have the good without the bad. Everyone is going to have their ups and downs, you just need to make it work and turn the situation around.
