I’ve changed my mind. Fat people would be allowed to vote as follows. If I were king of the world, I would set up a system.
There would be a test to assess knowledge and intelligence. It would include questions about history, civics, politics, math, science, chemistry, literature and other topics. It would also include some problem-solving questions. There would also be a physical test including weight and BMI measurements among other things. Everyone would take these tests if they wanted to participate, from voters to candidates.
A candidate’s scores would be shown on every ballot so voters would know if the candidate was a moron or fat or both.
For voters, your score would determine the number of votes you got, multiplied by how far you are from optimal BMI (which I’m going to set as 20, since I’m king of the world). For example, if your BMI is 30, your vote is worth 20/30 or 67%. If you score 75 on the knowledge test, you get 75 x 0.67 votes, or 50 votes. If someone scores 90 on the test and has a BMI of 20, they get 90 votes.
