"Thank you for your kind and thoughtful response" did get his attention.
In reply, he essentially asked how I expected him to reply, and restated his case.
I never expected to be so deeply discouraged, and I replied as follows:
I had hoped for the same level of discourse I extended to you.
For what it's worth, I have read through more than you think, and I am much more educated than you assume. Would you reply to Stephan Kinsella the same way? I believe he and I are in agreement. I am truly saddened by your continued behavior. It is true that Ian Freeman responded to your replies with unhelpful rhetoric, but he seems to have listened to good friends who talked him into behaving more civilly than he had, and offering ways to make you whole. I had hoped you would respond more thoughtfully.
People who quest for liberty disagree, as do others. I believe the measure of our character is often in our ability live peacefully and respectfully with others even when we feel we have been wronged or misunderstood. I know how difficult that is, as I have been the worst kind of hothead, and I work more than ever to improve my character. You may not know this from the context, but Ian Freeman and some of his co-hosts are partly to credit for this turnaround. It is never too late, in life, or in an altercation, to try to make amends--even if you do not believe you are the party who wronged the other.
What's more, this seemed to be a good opportunity to leverage peaceful libertarian arbitration methods, as they have been proposed, and even to "make lemonade" with the lemons of disagreement, by creating new endeavors that would not have existed before this. I suspect you have been presented such opportunities and have rejected them. How will free people live in a stateless society if, as Zeno would have suggested, we cannot mature, as better men, to meet the challenges it presents.
I am not angry. I am disappointed, and deeply saddened. Perhaps humankind needs another thousand, or million years of maturity before it can throw off the saddle of abusive monopoly force and peacefully coexist.
Addendum: respected him to reply --> expected him to reply
