Lol!!!! Please know I am not angry, I am laughing at you.
Everything you said here was some cope, I think your ego and narcissism isn't worth my time, the strawman arguments in there certainly aren't.

You were giving a denotative definition of morning originally, not a connotative one. This has nothing to do with prescribing language, but describing it. The ways we describe words can be connotative or denotative.
Dawn is when the sun rises. Morning is when you rise.
This isn't true though, morning is more than that (and most peoplewould not give this definition for morning at all). If I say "tomorrow early morning," or "at 5 in the morning" a night shift worker knows the time of day I am referencing. Further, night shift workers weren't being discussed.
You are absolutely projecting the contrarian thing.
Btw the existence of the "at" does not change the meaning from "best take it dawn than dusk." It means the same thing without the article.
