I've asked RJ to inform me as to what this "troll" business is all about, but I still do not see the point of adults calling each other names while having a vigorous discussion.
trolling is when you take a specific source you know will get an emotional response to an extreme position.
This one was tying Obama to an organization he has not supported.
Your initial post also puts Obama on the side of violence. Again this is disingenuous as he has said anything like that.
It is the work of a troll to start a thread based on no facts to create an unfairly negative apearance for someone with whom you disagree.
If you posted on other threads and weren't always incendiary, people wouldn't think you are trolling.
