It doesn’t matter, but for the record I don’t think you’re right to assert this is uncivil. I didn’t write it pejoratively, I thought he was focusing on an extraneous detail and missing the bigger picture, which is (imo) the meaning of obtuse. I think if you’re in battle mode then you’d be inclined to take it as an insult, but I don’t think it must be one (and I don’t think it’s wise to write as though everyone’s in battle mode - to cater to that)
