No need to crawl into a hole. I'm not sure about "standing up for
what you learned" is, because if someone taught you something that
wasn't right, you shouldn't automatically "stand up" for it.

In ATC, you'll be personally responsible for knowing the rules to the
letter, regardless of what someone told you. If the day comes when an
operational error is due to a misunderstanding of a rule or reg,
"that's the way I learned it" will probably not go over very well.
Best to learn that part sooner rather than later. It will be a fact of
life in your chosen career.
