The core issue here is you are asking for a 2nd opinion initially, but then engaging in a rambling battle with one lone moderator.
Your core question here is basically asking that others look at this closed question and add their thoughts. That is fair. That said, your question here on meta has become this rambling stream of consciousness that only confuses things more.
You state this:
“So my challenge is to convince Mokubai and her/his followers that the coin has another side.”
This is the core issue here if you ask me. You seem to be latched onto the idea Mokubai as the sole arbiter of why this question was closed, when looking at the close reason clearly shows:
“Closed 14 days ago by John, Mokubai♦”
The way this community works, is community members vote whether to close a question. Without any mod intervention, 5 non-moderator users can come along, vote to close that’s it; question closed.
If then the community feels that a questions should be reopened, there is a “Reopen” link at the bottom of the question. If community members vote to reopen the question, the question is reopened. Here is what that question’s status looks like:
As you can see, before you can even move onto “Reopen” the question needs to be undeleted.
So the takeaway you should have is:
This is a community effort.
In this case, your question was flagged by John as off-topic and then Mokubai (as a moderator) came in, saw that flag and decided to just close the question. But despite Mokubai doing that, anyone else can now come in and vote to undelete.
But that said, I will repeat what I said initially here as well as some comments I made regarding “this rambling stream of consciousness.”
In your initial question you are rambling and all over the map.
You asked question that is completely off-topic since nobody here can explain a manufacturing process like keycap design and production.
You state this:
“Give me a couple of days to collect and properly phrase my thoughts for the defense. I will edit this post then.”
This is part of the problem as well. Your inability to simply phrase a question in a clear and concise way and engaging in extended personal debate with yourself over this stuff.
This site is not about that. Nor do we have any insight into how manufacturing processes become standardized.
The core of your question is off-topic and all of the rambling “cruft” doesn’t help anything.
Seriously,
You also state:
“If the above are not convincing enough, then I don't mind deleting the question from SuperUser. Just still don't know where else to post it then.”
Where else to post it? Not on Stack Excahange. Maybe Ars Technica forums or Quora? But not here.
And for the record, the question was deleted on this site after sitting around with no “Ropen” votes coming through the automated “Community” user/bot.
