Specific Examples of Multiplying Maximum Extent by Maximum Intensity

If you want specific examples of the following stupidity:

There's also the belief that to determine the importance of anything, you can multiply its maximum extent by its maximum intensity.

you can consider the belief that open borders is a “dog whistle” for White genocide. If the extent of areas where white people can be found does not change but the maximum percentage goes from 100% to 90%, that means 10% of whites have been killed off, at least in StupidWorld. In addition, if another race is 100% in at least one area and can be found in all areas, that means it has taken over StupidWorld. (This also explains how the same people can claim that race X is taking over and that race Y is also taking over without seeing any contradiction.)

You can also find a similar idea in environmentalism. If at least one person has died because of pollutant X and if pollutant X can be found everywhere on Earth, that means the human race is done for … but enough about dihydrogen monoxide.
