What?! I quoted you! They were your words. OWN them! Be Proud! Why would you back off from it? You made a definitive statement about the attributes of someone you have absolutely zero knowledge. Judgement was passed!
But if you're going to back off, be a man about it. For example: "Hey, man, I went a bit too far there about someone I don't know from Adam's house cat."
Or, alternatively, double down in full. This additional response from you was lukewarm and pretty much a form of Surrender Cobra. "...I assume you know you better..." Ha! Geez, what a wimp out. Better: "I don't know you, but since my original attempts at insulting you were obviously ineffective, your mother was a hamster and your father smelled of elderberries!"
By the way, you did not bother to answer the original question. And putting aside all the school yard stuff, a serious question: why did that question trigger the response out of you that it did? And I'm serious.
