How about “I have lost interest in closing this discussion”, or even not answering at all? Anyway, that’s not what you indicated, you indicated that I had “won”, somehow. I’m not interested in winning arguments, I’m interested in finding out the truth. “(You have satisfactorily proven that) my (implcit) accusations were precipitated/groundless/undeserved. I now see where you are coming from (even though I disagree with your conclusions).” would have been my preferred outcome, “You are clearly insane and not worth talking to” would have been my least preferred.
