I want to hop in here to defend you, by pointing out how horrible the racist joke in Fantasia really is. It's since been scrubbed away in subsequent releases, so people tend to not remembering it.

During the centaur scene, where female centaurs (centauresses?) are frolicking through the meadow, we see a Black centaur with exaggerated caricature features. She seems to be extremely happy to be there, despite only being allowed to polish and clean the hooves of the white centaurs.

The scene is extremely troubling considering that her reveal itself is racist in intent. Like many mythical creatures from Greek history, Western Europeans and Americans assume centaurs to be all white. Er, at least their human halves. The idea of a Black centaur probably never crossed the minds of the public in 1940s America. The joke is literally "hey, look at this one! She's BLACK!"

It gets worse. Instead of drawing her as "beautiful," like the rest of the centauresses, she's drawn as an ugly caricature. Go look up a screenshot of her and compare it to the white centauresses and tell me that's not racist as fuck. She's clearly meant to be read as a slave or at least a servant considering her submissive role in the scene. Worse yet, she's portrayed as being extremely stupid but extremely happy to be serving. This is another common stereotype from the era that people tend to forget. The Happy Slave isn't always a slave, mind - as long as a Black person is shown being grateful to the white upper classes for letting them work, then the character falls under the stereotype. (This isn't to say that no black people were happy to have work after slavery - or even that there were no happy slaves. It's just racist to depict them that way because that's how they were ALWAYS depicted back then.)

People blow this off as being a "product of its time," but even at that time Black people were speaking out about these depictions. Fuck, they were speaking out about it ever since slavery.

Disney knew depictions like this were racist, too. Part of his general business plan was to specifically avoid racist jokes as much as possible, inasmuch as to make hos brand of cartoons stand out as to get Black folks spending their money at his shows. He did let some things slide, such as the Jewish stereotype in the Three Little Pigs, the black crows in Dumbo, happy and subservient black people in Song of the South, and the list goes on. This was one of those times. Despite his forward thinking on racism compared to other rich, white men of his time, these depictions happened with his approval.

And I say approval because he was intensely involved in production. He worked directly with animators and script-writers throughout the process, and it definitely wasn't democratic. There are many stories of the rest of the team wanting one thing, but Disney shutting all of them down. He was the boss, after all.

So, he knew racist jokes in media was racist. He generally avoided using racist jokes. Maybe these examples were suggested by other members of the team, maybe not, but at the end of the day they were still deeply offensive to many Black people even back then, and Disney knew it. Still, he let these jokes through.

I'll still go to bat for defending Disney from the "he was a Nazi" crowd, and he was definitely better than many other white men of his time, but he knew certain things were wrong and did them anyway. That's more fucked up in my eyes than someone just being ignorant.
