Kafke has a point. I'm not the only professional I know that leaves little unfinished nuggets in my "finished" work so that the overzealous producer can point at something and tell me to fix it. It's a rare creative overseer that can say "yep, you nailed it, invoice me" without insisting you tweak something.
At the same time, a non-clueless supervisor looking for make-work would look anywhere other than "how brown is Wolverine's girlfriend." BUT cluelessness happens.
Here's the shitty thing: Calling out cluelessness as racism (or calling out racism as racism) in a public forum like this will not diminish the cluelessness or racism. It will make the caller-out-of-racism radioactive to the point where not only will he or she never been hired again, it will taint the relationship between the supervisor and whoever recommended the caller-out-of-racism. Given a choice between "I want to be a better person" and "I don't have time to deal with this shit" "don't have time" will always win.
You are the master of your own destiny in a gig economy. Cartoons like this will ensure that you have a much higher profile amongst minority artists, minority-friendly companies and egalitarian-minded publishers.
I'm sure they exist somewhere.
