Roseanne Barr in March. : On Twitter on Tuesday, Roseanne Barr wrote that if “muslim brotherhood & planet of the apes had a baby =vj.” The message referred to President Barack Obama’s former senior adviser Valerie Jarrett, and in it Ms. Barr traded on age-old racist ideas about black people and primates. Then she shared some incorrect nonsense about Chelsea Clinton marrying into the Soros family. It was the kind of thing Roseanne Barr has been doing online for years. This time, however, the backlash was immediate and vigorous.
