I found the quoted blurb in the OP to be quite disgusting, but this is in no way a reasonable restatement of what Martin said. He did not say that he’s only here (in that thread) to slap sheep, nor did he say that was his principal reason for beginning engagement with that thread.
You’ve been an advocate of the principle of charity in the past - use it. The charitable, and IMHO reasonable, interpretation is, “I showed in in that thread to have a legitimate argument. Unfortunately, excessive group-think from the left made that impossible, so once that was clear, I was happy to slap the sheep around a bit.” Yeah, there are some problems with that, but not what you’re saying.
