Again, I apologize. It was a knee jerk reaction to being told I don't understand something without proof. I believe that also violates numerous guidelines:

> Be kind. Don't be snarky.

> Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.

And I disagree with:

> You've crossed noticeably into that here [emphasis mine]

I've only done that in 2 comments towards the same user who also behaved similarly towards me. All my other comments have been polite, constructive and filled with references.

I didn't mean you'd done it in more than 2 comments, just that it was a noticeable shift. Thanks for the kind replies!
