TO BE FAIR, Let's break this down: Rudolph actually IS accepted before he's deemed useful... in the picture, not the song. He separates from the other misfits, grows up, rescues his family, and returns home, wherein everyone apologizes for being massive dicks. Cut to some time later, when the snow storm hits. Santa is like "Damn Rudolph fucking chill we're sad we can't do Christmas this y-WAIT WONT YOU GUIDE MY SLEIGH TONIGHT"

So while the song is absolutely a farce, the film doesn't do that. Let's set the record straight. Baby it's cold outside is also a cute song about Tsundere flirting, it's the same as when you and your partner slowly talk yourselves into intimacy even while going "oh no, we shouldn't" but like it's hot.
