He's not saying "I'm disagreeing with you because I dislike you," he's saying "I dislike you because I disagree with your ridiculous PC policemanship and the fact that a lot of people actually take it seriously."
I disagree! You have the cause and effect mixed up. It's normal to dislike certain groups of people you strongly disagree with. For example, I imagine we both dislike gay bashers pretty strongly.
You, on the other hand, were suggesting that CamperBob2 was arguing with you purely because he didn't like you, which would be pretty silly if it were true.
