A Birthday Cake For George Washington

I never heard about this book until after it got pulled by Scholastic.  After learning about the book and situation the only problem I had with it being pulled was that I (and many others apparently) thought it was correcting an error that never should have been made in the first place.  

However, in a recent conversation about this, a person who agrees that the book is inappropriate (it does mention some of the hardships of slavery and the fact that Hercules later escaped, but only in the author's notes and not in the story itself) but this person also felt that Scholastic pulling the book was basically censorship.

I am against censorship, but I am also against a misleading book being marketed directly to children.  Hercules was a real person who ran away on Washington's birthday.  I could easily see a parent  mistakenly thinking that the book was about Hercules making sure the birthday cake was a success so he could have the cover to run away during the ensuing celebration.  This hypothetical parent, not realizing what the book was actually about could approve their child's selection only to end up with a book showing happy smiling slaves.

So does this fall under censorship, or just careful selection?
