What I don't understand is how many people don't understand and or refuse to look objectively.
Reverend Wright is a pastor. His job is to inspire, motivate, and provide spiritual guidance for his flock. As a pastor he may say things in order to inspire his people to achieve a certain type of understanding but his purpose is not inspire hate but action.
The reason he says what he says is to motivate people to take action upon themselves. If you someone paint a picture of a world that's out to get you and there is nothing that you can do to stop it, only to strive and do the best you can with what you have, than that's what you do. You don't sit (or at least you shouldn't sit) around and blame the "man" for your problems. You do something about them.
The reverend does not hate America. He hates what America does. He hates what it does to people and because his audience is black, he focus' on them. People who hate America don't live in America. Or if they do, they advocate destroying the government and attacking the country, not improving yourself with education and focusing on self-determination. That's what black liberation theology is (supposed to be) about. Unfortunately, like most religion, their are ignorant idiots who use what they hear as excuses, ignore the entirety of a message, and run their mouths off about how the white man has oppressed them and thats why they can't succeed. The majority of our species is foolish, ignorant, and likes to hear what it whats to hear. Pastors, politicians, lawyers, etc all know this and they sell their product based on that. There are very few people who can actually hear a message and glean what they need. Most conveyed messages are designed for these masses of people, with the hope that someone with a brain will get the message act, be it a political or religous message.
The only thing that I've heard about his sermons that sounded legitimately kooky was the bit about HIV being engineered. I'm sorry but we're not that good yet. HIV is amazing as virii go. It mutates so quickly. It's extremely elegant and is pretty much impossible to defend against unless you somehow make a vaccine based off the virus' base code.
