Bad things happen when governments pretend:
The U.S. government pretended that black people werent fully human and allowed legalized slavery to continue.
The German government pretended that Jewish people werent fully human and the result was the Holocaust.
Many governments pretend that preborn people arent fully human and the result is millions and millions of human deaths from abortions.
Many governments are pretending that homosexuality is normal and the result is endless problems.
Now the NHS is pretending that Alfie Evans is not fully human and they have, effectively, kidnapped him.
The U.S. government pretended that black people werent fully human and allowed legalized slavery to continue.
That was a compromise to limit the power of the slave states.
The slaves might never have been freed without it, because the slave states would have had more votes to fight the North with.
