There was no Weather Underground until fall of 1969.
They were a splinter group from the Communist front SDS.
It is erroneous to associate them with the 60s.
And they didn’t end their activities when the Viet Nam war ended. Ayers figured the revolution they wanted would require the murder of at least 25,000,000 Americans who would refuse re-education.
I think Bill Ayers is hiding under your bed. You should check.
