GRS = Genetic Rejection Syndrome
It's a problem with cloning, and with the genetic modification of embryos, probably delivered using mRNA
This is why all those Antifa people look so ugly
They are the violent failures of the genetic modification process that the parents used on their unborn babies
This is an episode of the TV seriesOuter Limitsfrom 1995. They reveal many of the Cabal activities using coded stories. For instance, ALIEN really means a foreign member of the Cabal elite, like a Rothschild, for instance. MARS really means US Military Intelligence. Some of the technology disclosed is exaggerated for story purposes, i.e. time machines do not transport your body, just your mind, but they can indeed take control of another human in the past. Demon possession is real but it comes out of a Cabal lab and the demon is someone from the future.
Travelers (2016)deals extensively with whitehat use of this time travel technology to fix the timeline.

It really is bigger than you can imagine
And outside of this board it is not likely to ever be disclosed.
