I don't know Rowell personally, but from her many social media media posts, I get the sense that she's both a tireless campaigner for social justice who's done important work calling out institutional racism in the soap industry AND a relentless egomaniac. I mean, her posts contain more "I"s than a Roman arithmetic textbook.
I think that's probably true of a lot of the divas we enjoy watching at a safe distance. If we had to regularly interact with them closely in person, it would be exhausting, because the diva would suck up all the oxygen in the room, leaving none for us.
