I don't personally see much of a distinction between "asshole" and "asshat" in this context, and I think the intent of your reply was pretty clear. Nor do I begrudge the comment--it comes with the territory of choosing such a username. But if you believe my characterization of that exchange to be false, my apologies. The link to the original reply was posted almost immediately after my comment, and so the context is there for all to see. I summarized it in a way that I thought would be entertaining to the audience.
