There is a diversity of views among the self-described alt-right. But the one unifying sentiment is racism — or what they like to call “racialism” or “race realism.” In the words of one alt-right leader, Jared Taylor, “the races are not equal and equivalent.” On Monday, Taylor asserted on NPR’s “Diane Rehm Show” that racialism — not religion, economics, etc. — is the one issue that unites alt-righters.

If you read the writings of leading alt-righters, it is impossible to come to any other conclusion. Some are avowed white supremacists. Some eschew talk of supremacy and instead focus on the need for racial separation to protect “white identity.” But one can’t talk about the alt-right knowledgeably without recognizing their racism.

And yet that is exactly what some conservatives seem intent on doing. For example, my friend Hugh Hewitt, the influential talk-radio host, has been arguing that there is a “narrow” alt-right made up of a “execrable anti-Semitic, white supremacist fringe” but also a “broad alt-right” made up of frustrated tea partiers and others who are simply hostile to the GOP establishment and any form of immigration reform that falls short of mass deportation.

This isn’t just wrong, it’s madness. The alt-righters are a politically insignificant band. Why claim that a group dedicated to overthrowing conservatism for a white-nationalist fantasy is in fact a member of the conservative coalition? Why muddy a distinction the alt-righters are eager to keep clear?
