How old are you? You don’t seem to have any recollection that China IS A COMMUNIST COUNTRY.
I am well aware of the fact China is one of the most totalitarian societies in the world. They have been our erstwhile quasi enemy in two wars. Most of the people live in squalor and their level of technology is at least 20 years behind our own.
Are you saying no one from communist countries should not be allowed access to the United States. Why?
