"tell that Dubya boy his pecker is in my pocket and to sign the goddamned marching orders NOW!"

Very academic. Definitely no arm waving or tongue flapping there

"I'm sorry. You are being a jerk. Perhaps you have been drinking, or perhaps you are that way naturally."

No personal attacks there.

"I guess if you voted for him, you have to believe him. Sad, because believing madness often leads there..."

No references to who someone voted for there.
