Antagonism with intent and agenda. It is easy to spot sometimes because of verbiage, vocabulary, and syntax. Sometimes I wish I could see your side of the server to double check IP addresses. I recognize quite a few here with more than one. And I see that they apply these depending on who they are addressing and the situation. Some are NOT conservatives but plants. But I was truly just curious, I knew it would bring out the jokers to have a little fun. :)
Some political posers certainly don't need more than one user name as one moniker is certainly enough to expose most of them. Why they'd change monikers to disagree or counter themselves seems a bit odd.
