It's like starting a thread saying 'who do you want to win the next election?', and giving everyone that chooses differently from you the thumbs down. I'm not a fan of what the Green party has done, so I said so, and as I made my post I already knew he'd give me the thumbs down :rolleyes...
People don't seem to use it that way. People generally only give the Thumbs down for completely stupid obnoxious posts. I think I'd only ever given about 10 in total, and I felt a bit petty doing that.
So Mustafa, every time you disagree with something I say you're going to give me a Thumbs down. You really are a tw@. Here, since you love the thumbs down so much, have 20 on me.
