Ehhhh. That might not be ENTIRELY unnatural. Uncivilized as f**k though.

It's unnatural in the way that money and clothing are unnatural. They're created by humans and no other species does it, that we know of

I meant that there's evidence that animals will shun other animals if they have an abnormal appearance from the rest of the group.

Yeah, defects... not color variations. (since we're speaking in generalizations)

True, but they don't build entire philosophical fortresses around it.

Indeed. We are the dumbest smartest beings on the planet

I claim that smart people are able to achieve levels of stupidity that dumb people cannot even approach.

Genius.

Imagine the level of stupidity I could achieve!

meanwhile papuan bird groups literally have slaughtered themselves to extinction because they were of slightly different color.

honestly though I agree, but if it's unnatural so what? Farming is unnatural. Domestication is unnatural. Guns are unnatural, we've been playing god for too long, why stop now?

To extinction.

You make an excellent case for why an enlightened society should function better than simple birds.
