I mean, it's the right place for it, but I'd say it is kind of in bad taste, given how correctness is such a big deal in cosmere theories. You don't just get to ignore Words of Brandons, you know? Joke or not, I'd say you definitely have opened the floodgate for being made fun of at the very least
So, yeah, I think it's in bad taste to post it. Maybe the Cosmere Theories is a humorless lot, but we're dealing with a universe that really does have a right or wrong answer to a lot of things.
