Back in 2004, Michael Moore wrote this [1]:

88% of Bush's support came from white voters. In 50 years, America will no longer have a white majority. Hey, 50 years isn't such a long time! If you're ten years old and reading this, your golden years will be truly golden and you will be well cared for in your old age.

If you don't think Michael Moore is a self-hating racist, simply substitute other races in similar scenarios until you see it. For instance, imagine that large numbers of whites are moving into a mostly minority neighborhood and someone is crowing about the lower percentage of non-whites in that neighborhood.

Moore is assuming that support for George W Bush was race-based when it was more a matter of money (his major supporters) and cultural issues (the GOP base). As his voters said at the time, Bush was a "good Christian man" who voters "wanted to have a beer with". Al Gore and John Kerry were effete librul snobs. If Bush had been black instead of white, most of his 2000 and 2004 voters would still have voted for him, all other things being equal. Those in Moore's sphere make things easier for Culture War profiteers like Bush by scapegoating whites, unfairly calling millions of people they've never met racist, and so on.

And, of course, other scenarios besides Moore's whites-in-their-place nirvana are possible:

Hispanics and blacks could join forces and decide - not burdened by political correctness as whites are now - that supporting all those old white people isn't something they need to do. In 42 years, who knows if the opinions discussed here [2] and expressed here will gain wide support? Further, rich whites might turn their backs on poorer whites even more than they do now and assist with or assent to plans to reduce benefits to poorer whites.

Or, non-whites might elect incompetent demagogues (such as a national version of Marion Berry) who'd do more damage to the U.S. than even George W. Bush did, poking huge holes in Michael Moore's racist safety net.

Or, whites might do with their minority status what many Hispanics and blacks have done with theirs: form a race-based movement and angling for spoils against their common enemies in other groups. Imagine a big, white umbrella white nationalist Teaparty that was like the National Council of La Raza rather than what they are now: an exclusionary, paranoid Koch brothers fan club. Imagine, for instance, that group demanding a form of affirmative action to make up for today's affirmative action.

Or, many whites might not like the way things are looking and leave for other countries, leaving the U.S. with fewer higher-wage workers and unable to sustain Michael Moore's welfare state fantasies.

Or, things might be somewhat like they are now, albeit with more scapegoating of whites, more affirmative action, and so on.

Or, it might all work out and the non-white majority might usher in a wonderful nirvana with whites finally knowing their place. That's what Michael Moore is counting on.

17-reasons-not-to-slit-your-wristsby-michael-moore
November 5th, 2004

He wrote that right after George W Bush's reelection. Here it is in context:

Dear Friends,

Ok, it sucks. Really sucks. But before you go and cash it all in, let's, in the words of Monty Python, “always look on the bright side of life!” There IS some good news from Tuesday's election.

Here are 17 reasons not to slit your wrists:

1. It is against the law for George W. Bush to run for president again.

...

6. Michigan voted for Kerry! So did the entire Northeast, the birthplace of our democracy. So did 6 of the 8 Great Lakes States. And the whole West Coast! Plus Hawaii. Ok, that's a start. We've got most of the fresh water, all of Broadway, and Mt. St. Helens. We can dehydrate them or bury them in lava. And no more show tunes!

7. Once again we are reminded that the buckeye is a nut, and not just any old nut -- a poisonous nut. A great nation was felled by a poisonous nut. May Ohio State pay dearly this Saturday when it faces Michigan.

8. 88% of Bush's support came from white voters. In 50 years, America will no longer have a white majority. Hey, 50 years isn't such a long time! If you're ten years old and reading this, your golden years will be truly golden and you will be well cared for in your old age.

9. Gays, thanks to the ballot measures passed on Tuesday, cannot get married in 11 new states. Thank God. Just think of all those wedding gifts we won't have to buy now.

10. Five more African Americans were elected as members of Congress, including the return of Cynthia McKinney of Georgia. It's always good to have more blacks in there fighting for us and doing the job our candidates can't.

[2] From Michael Savage in December 8, 1999:

To show you how deeply Marxian reversed logic has penetrated our society, let’s look at a recent article by a certain "Latino" gentleman. This Latino gentleman, if we can honor him with that title, states that with the aging of the white population in California, he doubts whether the Latinos - who he says are taking back the state - will want to continue carrying the older Whites on their backs. Of course, by "Latinos" we know he means activist Marxist Hispanics and the illegals they are exploiting for their socialist goals. The majority of Hispanics, naturally, the loyal Hispanic Americans, don’t count.
