Oh, you are surprised that when you make incorrect statements about someone, that they will respond with "think twice before trying to correct me"? Do you think I am going to say that you're right, when you're in fact wrong? Did you expect me to just let you say that I'm wrong, when I'm right? Haha.
I'm 100% right about that $1 statement, you are 100% wrong about it, so you did in fact need to think twice before making that post, as it would have saved you from the embarrassement.
I'm arrogant? I'm not the one making false claims and not acknowledging that I'm wrong even after being pointed about it. Think about how arrogant that is. A modest person would admit being wrong, possibly appologize for making the false claim, and carry on.
