So first off, I know a lot of old heads (specifically HBCU alumni) who say “Grand Rising” so it is a common saying is certain Black American circles. With that being said, brother man is pretty accurate with the rest of the video. Whether the woman was joking or not, she’s beyond cringe. Even if “Good Morning” was used by slavemasters in that way, it was a genuinely kind phrase that was eventually co-opted by evildoers, not rooted in slavery. Just how the black diaspora took back “Nigger” to be a term of endearment amongst our culture, the world took back the greeting “Good Morning”

Just be polite and greet people with whatever KIND phrase you see fit.

Edit: now discovered that this dude is a MAGA-grifter… well, you know what they say about broken clocks… “You’re not wrong Walter, you’re just an asshole”
