Since we're educators, I think this is appropriate to post here. Here is
Unbearable, these tributes from the weeping bourgeoisie on death of John L
Lewis. SNCC never forgave him for censuring his own speech at the 63 March
on Washington, at request of CIA-financed Bayard Rustin and ML King, which
called Lewis's original speech too radical, and some labeled it
"communist". He called for a march through the South "like Sherman," and
for no support to Democrats or Republicans, and that SNCC wouldn't wait for
the courts or the president to act, a revolution was needed." Later of
course, John Lewis was in the wing of the civil rights movement that was
co-opted into the Democrats, where he remained for the rest of his life.
See the two speeches here, the one he wrote, and the one he gave, after
being told to "censor."
