Even the introduction to Tarzan of the Apes in later editions notes that parts of the book are pretty frickin' racist, and were influenced by eugenicsnote Constantly referring to non-Caucasians and lower classes as lower orders of humanity and pseudosciencenote The notion that you can use fingerprints to determine race, as well as the overall Lamarckist slant..
In the original books, Tarzan liked to use rope as a weapon, dropping nooses down from the treetops to bind and choke his foes. This isn't so bad on its own, but the fact that Tarzan often used dangling nooses to hang and strangle the African natives from trees draws some uncomfortable similarities to lynching. With this in mind, Tarzan's fondness of rope is understandably left out of most adaptations.
