Just how is this impolite and fussy?

"Birds are theropod dinosaurs as much as dogs are carnivoran mammals. The avian group is a branch within the dinosaur family tree, since birds developed from small coelurosaurian theropods. The main characteristics of theropods are hollow bones and three-toed feet, which birds possess. Prehistoric theropods even had wishbones and brooded their eggs like modern birds."
