(mature only)Saggin spelled backwards—what do you think?

I am a 22 year African American male who is in the professional world (I work as a technology istant). I never was the type to sag. Someone emailed me about the origin of “saggin” and claimed that it came from people spelling “saggin” backwards. Honestly, I think it is very bogus. “Sagging” (the word) isn’t only used to reference to lowered pants but things that are drooping. I think it is a coincidence that someone’s slang formed a word that was able to be spelled backwards. The word “sagging” was created before the idea of imprisoned males wore their pants low. Such a word could be in a sentence to refer to sagging , sagging face muscles, and sagging skin. Is this not distorted information that’s used to stimulate hatred on another race?
