It's almost like humans have evolved next to every other animal on this planet, and it's almost like... mammals share certain aspects of how they experience life. Including liking/disliking/hating certain people/animals.

Humans love to anthropomorphise animals when they do human-like things or express certain emotions. And most likely said animals do feel something related to those emotions, because after all, their experience of this mortal coil isn't that different from ours. What they seem to lack is the understanding of those emotions, at least on a human-like conscious level.

In reality, we shouldn't be anthropomorphise animals, but realise that 90% of the things we do, animals do too, it's just that we have a conscious understanding of those things that animals lack. Or, sometimes, it's the other way around. I mean I don't see penguins or donkeys or bulls being homophobic and trying to kill other animals just because they happen to be attracted to the same sex, for example.
