Why are you still responding? What kind of rhetorical trick is this? "I'm not going to talk to you, because there's no way you and I could ever see eye to eye. ..... except now I'm going to call out some part of your behavior I don't agree with." I can't figure out what you're trying to accomplish; this is a new form of internet snark for me.
