"Uncle Chang," God bless you.
We don't know his real name, only his Twitter handle, and he isn't yet a star with just 1,044 followers (that'll be rising fast).
But Uncle Chang created an extension that changes the word "white" to "black."

Chang's "Racism Simulator," available here, "converts 'white' to 'black' for maximum outrage," the pitch says.
"Ever see articles bashing certain groups and thought to yourself how totally not okay it would be if the groups were replaced with another group? This extension swaps the groups being written about on HuffingtonPost, Salon, Buzzfeed, Jezebel, and Gawker to show how much racism, sexism, and outright nastiness they get away with because they chose to target an 'oppressor' group."
The results are indeed "hilarious."
"5 Reasons 'black pride' is always racist." "Black guys are killing us: Toxic, cowardly masculinity, our unhealable national illness." "Black fragility is real: 4 questions black people should ask themselves during discussions about race."
The list goes on and on (click here, then click on page to enlarge). "29 Things Black People Ruined." "Black people are more racist than the realize." "Yes, Diversity Is About Getting Rid Of Black People (And That's A Good Thing)". Ha!
The extension is a wonderful exercise in the old flip-flop, like, "What if [insert opposite here] had said/done that?" It's point is also easy to grasp: What's racist on one side, by definition, racist on the other. Simple.
Posted on reddit.com, the entry so far has just 61 comments. One reader said, "Not sure if funny or horrific." And another got straight to the point: "racism is racism. but somehow it's allowed/encouraged if targeted towards white people, funny really."
Hilarious, in fact.
