This is what the media calls the "Ayers" matter. This is what Obama says happened when he was only 8-years-old; and both are lying to you. This is what the media tells you was only bombing and they never really hurt anyone. They are lying. The whole very ugly and deadly mess is still here today. You see, Hitler learned in his unsuccessful Munich putsch (violent uprising), that he had to seize power by almost lawful means. Ayers and Obama also learned that to create a Marxist America, violent means must change to lawful (well, kinda) means to achieve their ends of a Marxist state of America.
"Ayers" is a very sterile Chicago media subject titling. The Weatherman were involved in a declared war on America to achieve a violent transfer of America to a Marxist communist stateless and classless society. They rampaged and destroyed property and then escalated to bombing and murder. You always hear "Ayers", but you don't hear about his wife Bernardine "Dohrn". Testimony before Congress, plus "Ayers", have indicated his wife "Dohrn" murdered a San Francisco police sergeant, and injured many more in a bombing where "Dohrn" constructed and detonated the bomb herself. She was evil and sick, and her unrepented present render her the same.
You'll find that Michelle Obama and "Dohrn" worked together in 1988, several years before Obama admits first encountering "Ayers". You'll see that Obama was 19-years-old when "Ayers" and "Dohrn" came out from underground. You'll see that Obama was in his twenties during the Weatherman robbery, and murder of three, in a failed Brink's robbery in New York, and during the subsequent investigation and trials. This is a chapter that brings out what Obama really hangs-out with, and that this relationship very likely has gone on for twenty years. And there is much more to read here; and it gets more gross.
