The first album was written during colonial times and reflects the consideration European people had towards natives at this time (ie. they would be savages waiting to be "enlightened"). This is considered a racist behavior today and some people are offended by it being still available for young children without any censorship, while others see it as an historical document that should remain intact.
Maybe because I grew up with a partial collection of it that I inherited from my brothers.
Can you explain what's disturbing about it?
