You have no idea who I am, and don’t know a thing about me, my life, my upbringing, my cultural roots, nor anything about where I stand on the issue we’ve been discussing.
You’ve proven that by your responses to the several salient points and bits of information I’ve imparted to you, so far.
I told you to walk away, because I’ve realized that you’re not actually conversing with me. You’re carrying on an argument with some nebulous opposition viewpoint in your mind. I’m not even part of the conversation.
You’re not interested in talking with me, but feel free to continue arguing with that specter in your mind.
