Half the Homo sapiens population, i.e., 4 billion humans, has an IQ lower than average.
Human fucking garbage.
And these are humans who are not just at the bottom of society; it's assholes at the top too.
Humans should be breeding for powerful genes for IQ and beauty and other strong, healthy genes, not creating useless garbage humans who created & uphold a stupid, unnatural, parasitic system of living.
Get rid of the dysgenics & good humans will get rid of light pollution, among other things.
