Obsession with crime and punishment. Rampant cronyism and corruption. Rampant sexism.
These are among the "early warning signs of fascism," originally written by Lawrence W. Britt in 2003, and displayed on a poster at the U.S. Holocaust Museum in Washington, D.C.
A photo of the sign posted to Twitter Monday afternoon has since gone viral, retweeted more than 140,000 times and liked more than 193,000 times.
