Chris Rock declined quote

Greetings,

my submission 220408-194254-934000, was declined and the real life quote is the joke "Jada, I love ya. "G.I. Jane 2", can't wait to see it, alright?", I'm assuming it declined because it can be perceived as malicious but another joke he made at a different year at another Academy Awards was "Jada boycotting the Oscars is like me boycotting Rihanna's panties. I wasn't invited." Feb, 2016, was approved even though it has a sexual context was approved? And this video is my source for the declined quote:

can someone in the imdb staff elaborate why one joke that was sexual in nature was approved and the supposedly malicious joke was declined?
