The social justice left is happy to say that everything is the fault of white men. Well in a sense that's true because we are the ones who are responsible for it all. We're responsible for the food you eat, the car you drive, the phone you stay permanently glued to. We built the building you live in, the power grid that lights it, and the water system that keeps it clean. If it moves, and even if it doesn't, white men were responsible for its creation, its manufacture, and environmentally safe disposal. We did it all.
And if you get rid of us, then it's all going to go away.
Now no one is seriously making the argument (no one worth listening to anyway) that America should somehow get rid of all white men. And even if they did, the Army (which by the way is the world's largest) has combat units that are disproportionately white, wouldn't make it particularly easy. But if you really want to live in a world where all the white men are gone there are a wealth of options available for you. I'd suggest Liberia which was specifically set up as a home for repatriation of black slaves. There you cn be free of all the reliable electricity, clean water, and comparatively efficient healthcare that white men have inflicted upon America.
To quote a friend of mine who did some business there back in the day, they do have 6 foot 4 transvestite cannibals in wedding dresses who carry machetes. So no matter how marginalized and oppressed you are, I'm sure you'll feel right at home. Just think of how oppressed that machete wielding cannibal must feel.
