Or, as "The Man" so eloquently put it:
"Stan's Soapbox: Bigotry" printed in Marvel books dated December 1968
(this one came from Fantastic Four #81)
Give or take a few Civil Wars and Superhuman Registration Acts here and there, that spirit still resides in the contemporary Marvel Universe. Take, for example, Storm's speech in Black Panther Annual #1, which celebrates the work and the spirit of Dr. King and other workers for tolerance, equality, and love:

No, no, no, not that one, but rather this one:

Yes, it's Kral, the Skrull world where they're all cos-playing as 1920s gangsters, with some sidetrips into Ancient Rome gladiator fights that pit the Thing against Torgo.
No, no, not that one, but a giant super-strong robot/cyborg type of guy who learns about humanity from Mister Ben Grimm just in time for Reed, Johnny and Crystal to arrive on the planet, dress like extras from Bugsy Malone and overthrow the Kral government to get themselves a piece of the action:

And 'round about now you're asking me What the Sam Scratch does this have to do with Dr. King, Bully? And that's a very good question. Y'see, eventually the Fantastic Four re-visits Kral, but it's the FF featuring Black Panther, Storm, The Thing and The Human Torch. (Poor Sue, she's always missing out on the Skrull Gangster Planet!) Except, just like Captain Kirk wondering what kind of civilization would spring up after the Enterprise left Sigma Iotia II, here we get to see the aftermath of the FF's previous visit. Yes, on Kral it's now roughly the 1960s and we have a Skrull who has taken on the identity and the ideals of...wait for it...

A group of Skrulls has begun a civilization-changing revolution against the regime of Skrull gangsters by becoming Dr. King and the only X-Man who was never on the team:
Of course the underground revolution wins and the FF escape for home, leaving plenty for room for an eventual sequel (c'mon, send the Runaways there!), but not before plenty of moral discussion and some good old fashioned arena-fighting action. It's a neat little parable, much in the vein of the better episodes of Star Trek, about how alien planets are sometimes not so different than our ownboth hate and intolerance, and peace and love, can come to blows throughout the galaxy.
Mind you, as much as Storm reveres Dr. King's views, a mutant superhero and African queen (no, not this one) has gotta fight for what a mutant superhero and African queen believes in:
