If I had to choose a race to be eliminated to get the alien tech, I'd go with potato sack. Some people might miss it, but I feel like it's time to let that one go.
Reminds me of that Black Mirror episode when people could post names of people they wanted to be killed and every day the most posted person were killed. After some time, the man behind that killed all of the people who voted for anybody.
I'm concerned about the amount of people in this post that aren't just saying that None is the correct answer, but are instead trying to come up with a race to pick.
Majority white and black would vote for each other
And nothing we didn’t already know would be revealed
Also when an advanced race capable of killing the entire species says “you must” do something then I don’t think it’s racist to vote and I don’t think saying “none” is allowed because it defeats the purpose of the experiment
As there's only one race, I guess everyone who chose anything but none gets the human race symbol (???) tattoed on their face. Still would be fun to see who chose to have other humans killed.
Now, if the OP in 4chan meant ethnicity, that's a different story.
What if, instead of a tattoo, everyone who voted just becomes that race?
The logistics would be tricky. Aside from the fact that race doesn't exist, people within an ethnicity don't all look the same. And would they still have the background of however they were originally born?
That might be kind of convenient actually - racist assholes of all colours will label themselves and probably kill eachother while (hopefully) most of the population's foreheads will read "None".
Immediately though of one of those races of dog or cow that's been inbred to the point that their existence is torture already. I didn't think of humans.
