Do you think all black socialists think alike? Socialism has many forms, just as capitalism does.
Do you think "identity politics" is always used in the same way? Barbara Smith disagrees with you:
"I am often disheartened, however, to see support for identity politics and intersectionality reduced to buzzwords. I am supporting Bernie Sanders for president because I believe that his campaign and his understanding of politics complements the priorities that women of color defined decades ago." --Barbara Smith
Note that most identitarians supported Clinton and Warren because they were women.
