Your lack of manners only impacts yourself.
Nobody asked you for an apology. You have fully lived up to the low expectations I had for you.
I don't pretend anything. I said what I think. You can dig as deep a hole as you want, but you can't make me climb into it.
Here's something I have observed: You have the interpersonal skills of a fanatic. No one is converted by insult. But you have no interest in persuasion, only in vindicating your own point of view to yourself.
