The yahoos in the deep south of this country have access to knowledge. The ones in Iraq or Iran don't. So I think there is a difference between choosing not to learn and never having the opportunity.
Your comments on us putting the ones in power who do this is probably spot on. (I chose not to delve deeper, so I too am guilty of choosing to be ignorant on something.) But, the fact that you or anyone else in America can get that in depth about it proves that we do have access to the knowledge.
As far as electing them, so we are at fault, too. That's iffy. No one ever runs on a platform that says they are going to continue to cause world suffering. And until they are elected, how would we know if they would do that or not? Really, I'm asking because I don't know. I don't think we can trust anyone in politics, but what do you do? Is Wayne Root someone who would continue this? I like what he stands for, but it could all be lies too.
