"I would free them all to avoid this war."
"I would kill my firstborn to avoid this war."
"I would take a dick in the ass to avoid this war."
"I would lick UB's sweaty balls to avoid this war."
ALL but one of these statements was within his power to do. Well, two unless you are THAT old
So what did he really say?
"I would end global warming if it would avoid this war."
"I would save Trayvon if it would avoid this war."
"I would bitch-slap Snookie if it avoided this war."
IMO, he was speaking to a hot topic of the time. A PART of the reason the war was fought. Not "the" main contributing factor.
There were several reasons for the Civil War. Slavery was a part of that. And was used as propaganda, just like the other causes.
