Bigotry and hatred, fear and loathing, are on the rise. Vulnerable groups are being targeted. It’s happened before. Decades ago, speaking to the National Jewish Congress, Dr Martin Luther King, Jr said, “My people were brought to America in chains. Your people were driven here to escape the chains fashioned for them in Europe. There are Hitlers loose in America today, both in high and low places. As the tensions and bewilderment of economic problems become more severe, history's scapegoats, the Jews, will be joined by new scapegoats, the Negroes. The Hitlers will seek to divert people's minds and turn their frustrations and anger to the helpless, to the outnumbered.” Recorded at the University of Colorado.
