As a black man, I LOVE IT. And I think I get the vague meaning:
“...Doing nothing, is not an option.”
Let’s face it: White folks are the ones getting crapped on about everything. I read it as, “How much longer are you gonna take this crap?”
It could be interpreted as a nod to the industriousness of white people or mocking the historical meddling of white people. As you said, it could be a call to action, or it could be a fatalistic acknowledgement that white people will do something, like it or not.
