That is an incredibly weak rebuttal. I was going to CU Boulder in 1974-75 and there was a CIA recruiting office right there on campus. Somehow I don't think that would have been the ideal location to find world-wise people.
A weak rebuttal to this? ...
"way way way back in the day of Bill Ayers coming to prominence via the Weather Underground, there were plenty of college kids who considered him to be an obvious government plant"
So you also think Bill Ayers may have been a U.S. government plant? That he wasn't really a revolutionary communist, domestic terrorist?
