The Arizona "Papers, Please" law is a prime example. The more laws that are passed because of fear, ignorance or racism, the closer the United States comes to replicating whichever totalitarian regime the conservatives and their right wing militants are most afraid of.

Many years ago, back when I was married, I lived in the Catskills and worked at the Granit Hotel as a busgirl and server.

Since I grew up with a steady diet of science fiction books, I believe that there are other forms of intelligent life not located on the planet Earth. How do I know they are intelligent?

On the other hand, the majority of us would probably make good slaves.
"If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said.Truer words were never spoken.
