If you choose RC Cola, you get RC Cola. If picking a soft drink was like the elections, you wouldn’t want to choose RC because you’d still get Pepsi or Coke and you’ll just be throwing away your ability to influence it to be the one with the lower concentration of cyanide.
Meanwhile nobody wants to acknowledge that the soda machine is already cooked and needs to be put out to pasture when asking for “no cyanide, please” gets you accused by the supposedly “civil, thoughtful” soda drinkers for being foreign plants hellbent on shoving the soda they don’t like down their throats, instead of regular people who think not dying of cyanide poisoning might be pretty cool.
