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.
