...riiiiiiight up until the power doesnt work anymore.
Then all the teaching and humanizing means on a stick. We are animals and we prove it everyday across the globe.
Whether its a country that executes people in the 10s of thousands every year (China), the butchering of your neighbors who you broke bread with less than year ago (all of Africa, really), the stupid ing Climate morons impressing their gained wisdom onto the undeveloped world (the entire West)...these examples can go on forever.
Humans, by design, are advantageous, cunning animals. We would shirk our own kind if it suited our purposes and we do it everyday, some in big ways (murder), mostly in small ways (lying once every 40 secs).
Dont pretend that this truth can be educated away. Not in this eon, anyway. By the time humanity reaches a point where the world's problems are less apparent than they are now, we had might as well not even call ourselves human...if we make it that far.
I sincerely doubt it.
