I'm about to kick a hornet's nest.
Why does this fandom gatekeep and fiercely protect Jazz in particular so hard? No matter what you're making Jazz do there's a legion of fans who'll go around and say it's racist, thereby discouraging people from using him, when he's a really awesome character and should be in more fics/continuities. I've sometimes found myself having similar worries about putting Jazz in stuff, worrying about whether or not people are gonna call the portrayal racist (my main thing is that I write a lot of smut, so I sometimes find myself worrying that the pearl-clutchers are gonna think I'm "fetishizing" black men by putting Jazz in there) and that just makes me think... isn't it more racist to discourage people to put Jazz in stuff at all? By fiercely guarding him like this you're going to get a lot of people to decide it's just not worth risking being called racist and just not put him in their fic, fan continuity, etc.
Jazz is awesome and we should encourage people to have fun with him, not censor themselves out of fear of the "everything with Jazz in it is racist" crowd.
Another weird thing I noticed: Why don't people do this to Blaster too? He also has heavy ties to American black culture, but you don't see people calling everything with Blaster in it racist or bigoted or whatever. He's not nearly as fiercely protected as Jazz and I can only assume it's because Blaster didn't appear in as many other Transformers continuities as Jazz has.
