Bill Ayers is a throw-back to the type of leftist who wasn't afraid to draw blood in pursuit of their wicked ideals. That sort is the exception, rather than the rule these days.
It's obvious we view history differently (to clarify - leftists = statists).
Mao killed over 60 million in various ways - most in my lifetime. Add in the other 20th century statists and the number dead eclipses 150 million.
If you read this thread, Freepers point out that there has been a successful pogrom of senior military leaders during the ObaMao tenure.
Statists gush "compassion", but in actuality, they have no regard for human life. Abortion, slavery, starvation, war, terrorism... they worship man, not God. They are not afraid to terminate life. They have a large quantity of highly trained, funded, equipped, domestic and international "useful idiots" from multiple taxpayer entities to carry out their assassinations.
