No, the definition of fragile is that if you use something in a wrong way, it breaks. But Emacs doesn't break. It obeys and keeps running.
With your reasoning, all software that gives you a choice, anything that can be configured, all programming languages etc. etc., become fragile, because as soon as someone says "I did this but I didn't like the result," your case has been proved. In other words, it is a circular definition.
Anyway, I didn't mean learning experience in a condescending way. The user I answered indicated himself that he was learning---and we all are, when it comes to Emacs.
