Hear me out in this early bird thought of mine
You're an eugenicist, you only want the physically best amongst humans to survive (exceptions made for the fat, rotten, adrenochrome-guzzling billionaires that bankroll you and their more-inbred-than-the-House-of-Hapsburg-living-in-Alabama families of course)
So you make up a drug to kill and sterilize as much people as possible, and the mockingbird media and the jackboots will do their part to force as many as possible to take it.
Aaaaaand it's killing young, athletic and perfectly healthy individuals while the 400-lb neon-haired SJW's with a permanent double IV drip of Ben'n'Jerries and the malnourished vegan soyboys are still out there.
Makes even less of a sense if you're a white supremacist, in which case the shots should be completely decimating places like South America, South-East Asia, China and India.
What gives ?
You know in the old western movies where the bad guys come to town and just start indiscriminately killing people in the streets? Then they camp out in the saloon and take over the whole town based on the fear they deliberately created. Could this be the deep state "show of strength"? Where they will shortly turn course and say to us "look what we are capable of........ comply or it happens to YOU".
