Look.

This scheme is so goddamn brilliant, 13,000 of the smartest people working on this has no doubt produced a doozy. They were paid well.

The shot is a retrovirus that inserts a RECESSIVE sterilizing allele. And in some it's a DOUBLE DOMINANT allele.

some are recessive, some are double recessive, some are hybrid/heterozygous dominant, some are homozygous dominant.

this way some people believe they are NOT sterilized and so they don't CARE , they are THRILLED the other people are sterilized.

They won't know they are sterilized til their KIDS grow up to be sterile, they won't have grandkids and SOME won't know til their GRANDKIDS grow up, holy FUCK this is diabolical.

It's all been layered, time released.
