Wouldn't it be more racist to specifically avoid such a storyline because the actor playing Worf is black?
Also, if Star Trek is racist, then wouldn't that mean Saints Row is racist too? Michael Dorn played Maero in that series, who wasn't just an a strong brute, but also a criminal.
What would have happened if Michael Dorn got turned down for the part of Maero because he's black?
Mass Effect 2 was probably racist too, as they typecast Michael Dorn as Gatatog Uvenk, another warlike brute who no doubt would have been raping all the women given half a chance.
What about Stargate? That series cast both Christopher Judge and Isaac Hayes as big strong warlike brutes. Was were the writers of Stargate being racist because you could draw parallels between the black Jaffa and the stereotypes of the 'Savage Zulu' and 'Enslaved Negro'. Should they have just made all of the Jaffa white to avoid being racist?
It seems to me that specifically denying actors employment and certain roles in works of fantasy and science fiction, based on their skin colour, is pretty wrong.
Anyway, going back to that episode of Star Trek TNG. Why are you solely focusing on the racism against Michael Dorn and black people. What about the fact that Patrick Stewart, who played a Frenchman, devolved into a cowardly monkey? It was just one step away from having him each cheese and wave a white flag.
Come to think of it, Star Trek is pretty racist. All of the leaders, officers and academics are white, who in turn are served by the token black muscle brute in Worf, Space Stevie Wonder in Engineering (oh, just because he's blind means he has to be black too) and Whoopi Goldberg, who is cast as an alien, but is basically a subservient house servant, getting drinks for all the white masters and being at their beck and call.
You can make anything racist if you try hard enough, but you're probably right, we should ban this sick filth.
