...to think "they're not [fully] human" would imply significant cognitive deficiency. I mean, it is one the world has been plagued with. You can find past examples in constitutions viewing slaves as lesser and forbidding Jewish folks from a country. In modern times - at least in the US - folks use it for immigrants and prisoners and to a lesser extent, poor people. And sure, a deficiency, but I'm pretty sure it is one folks choose part of the time. Admittedly, however, I think what the article refers to is kind of a mental shortcut folks do unknowingly - one of those things that usually just helps us process the world around us. A car isn't full of people, it is a thing. A bike is a mini car on wheels. Walking folks, even with a bike, are people, though.
