All schools should just be named “Progressive Youth Indoctrination Center #xxx”. School colors can be grey and black. The mascot can be a circle with the school number in the center.
Problem solved.
If you haven’t yet, watch Community. Their mascot was a human bean. It was an androgynous human shaped entity in a flesh colored (microagression intended) body suit.
They would probably have to start the numbers at 10,000 because many of the smaller numbers are racist, homophobic, etc. For example, any number less than 2015 is homophobic because gay "marriage" didn't begin until 2015.
