There are plenty of overt white supremacists on the right, but they aren’t the mainstream. After all, America, unlike any European or Asian country, is a nation of immigrants, so trying to pin down an American identity purely in racial terms is not realistically possible. There is no practical way to make the tens of millions of people of color just go away. The best the right can do is to lock in the existing advantages of white people by pretending that America has completely shed its past, and by controlling further changes to the nation’s racial composition.
How will this be done? First of all, by precluding additional immigration, and by deporting as many illegal immigrants as possible. Second, by ordering public schools to teach students that racism in America was just a blip and is long gone. Third, by completely eliminating all forms of affirmative action. Fourth, by defanging the Voting Rights Act. Finally, the New Right is a pro-natalist party; perhaps the problem can be solved by having lots of white babies.
None of this will make public discussion of our country’s racist past impossible. Will the right go so far as to censor the ideas of adults on racial issues? That’s the frontier on this point; it will be discussed at some point if the right’s political position becomes unassailable.
