I believe you that it wasn't your intention, but when you address someone in the second person while commenting negatively on their perspective and understanding, it's going to land with a lot of readers (as it did with me) as personally pejorative. It's common for commenters (me too of course) not to perceive the provocations in their own posts, while being extra sensitive to the provocations in others' posts. If the skew is 10x both ways, that's quite a combination. It's necessary to remember and compensate for the skew, a la "objects in the mirror are closer than they appear".

Edit: total coincidence but I just noticed https://news.ycombinator.com/item?id=47115097 and made a similar reply there. I thought you might find this amusing, as I did.
