Well, Meg, I don't understand what the difference is between the "artifice of polite reason" and actual polite reason, except maybe that you disagree with him. It is plainly evident above that Heartbreak of Psoriasis was polite to you throughout -- even after you insulted him several times.
Doubting his motives is no excuse for what you did to him in #67, #70, #74, #82. In #111 you basically suggested that he leave.
Finally, what does imagery of "the gurney was elevated to the Cross" really mean? I can think of several things that he might have meant, some of which I may even agree with. But why not ask him politely, "Heartbreak, that sounds strange, what exactly do you mean by that?"
Let us all remember that there are real people behind these posts. And though I hesitate to add this, since I myself have not lived up to these words, we will be held accountable to them:
The good man brings good things out of the good stored up in him, and the evil man brings evil things out of the evil stored up in him. But I tell you that men will have to give account on the day of judgment for every careless word they have spoken. For by your words you will be acquitted, and by your words you will be condemned." (Matthew 12:35-37)
Best regards.
