:::"WP:DTTR is an essay." I didn't say anything about WP:DTTR. I pointed out what is a practice according to members of the community, something I would not merely dismiss out of hand as you seem to do.

"At what point does an editor here pass your threshold for what constitutes a non-newbie?" As for Delta/Triangle (sorry, I don't know how to make triangles on my keyboard), I concluded at the time that he was a newbie for the reasons I mentioned above. It was an explanation of my perception at the time, and not some type of value judgment. But if you really want an answer to your question, I'd say an editor is no longer a newbie when they have a reasonable command of how Wikipedia works, such that they do not make false accusations of copyright infringement, make a point of communicating with image uploaders, and familiarize themselves with the right way to communicate with members of the community.

"If you believe images should be retained without there being a rationale for that use present..." Thank you for making it clear that you either are not reading my messages, or are being deliberately churlish. I didn't say anything about images being retained without a rationale. I already explained clearly above the matter regarding the rationale, and if you're either too illiterate or too lazy to read and comprehend this, then perhaps you should not engage me in discussion.

I made the edit summary that I thought was appropriate, as I'm quite tired of obnoxious deletionists like Triangle who make false accusations and no attempt to communicate with others, as well as persistent liars like yourself who think repeatedly putting words in other people's mouths constitutes "discussion". If you don't like my edit summaries, then tough shit.
