Sadly, the main way you can tell this is satire is that it sounds a lot more toned-down and reasonable than the actual spew coming from the likes of Luddite, Limblargh, Gangrene, Torquemada, and the rest of the Living Dead. Just this modest proposal:
We must fight. Today, a white male child will be born into an oppressive society where the color of his skin will only be a great advantage, not an incomprehensibly powerful advantage. That child will see that there is now extra competition out there between himself and his dreams. That child will be born into a society that - while understanding his cultural values and belief systems - will no longer automatically fearfully submit to them. That child will be destined for a life of dreams and promises that will only very likely be fulfilled. The guarantee is now gone, and we must get it back.
My white male friends, we shall overcome. We are a theoretically oppressed majority, but our voices can be heard. White men, spit the imperceptibly less silver spoon from your mouths and yell to the skies “The White Man will rise again! Power to the white male.”
Thank you, and I have retained counsel, several bodyguards, a maid, hairstylist and personal valet on this matter.”
