That’s not a common meaning, it’s the morons’ meaning.

Cambridge dictionary has both definitions, the more common one first

something that lives and moves but is not a human, bird, fish, or insect

anything that lives and moves, including people, birds, etc

Wikipedia has this to say:

The word "animal" comes from the Latin animalis, meaning 'having breath', 'having soul' or 'living being'. The biological definition includes all members of the kingdom Animalia. In colloquial usage, the term animal is often used to refer only to nonhuman animals.

So your argument here is basically "But I have big brain because I use the correct word as defined in biological science as opposed to the morons that use language colloquailly on the internet". Good job.

Showing that you see animals and humans in the same category.

As does anyone with a brain.

I mean yeah sure they are in the same category in the sense that both have evolved from the same basis. But humans have evolved further than animals, which is why there is commonly a distinction made between humans and animals without having to say non-human animals.

Examples are:

• animal cruelty
• animal rights
• animal shelter

Obviously none of these relate to humans, because everyone with a brain uses the term animal to mean life that is not human.

Are you braindead?

It sure feels that way when I talk to you, because you are draining my will to live.

behaviour [SIC]

Imagine not knowing that behaviour is a valid spelling of the word everywhere but the place that had to drop the letter U from words to feel special. Time to make a few more rounds in the spelling bee
