The concept of a “hate group” could be useful. In practice, however, it is like the concept of “hate speech,” applied to shut down heterodox speech and confine the public square to dissemination of officially approved thought. The concepts somehow overlook the likes of the hilariously misnamed Southern Poverty Law Center and its works, which direct something far beyond the Orwellian Two Minutes Hate to the likes of Charles Murray and Ayaan Hirsi Ali. If there is such a thing as a “hate group” — as I say, it could be a useful concept — the SPLC is it. Indeed, I think it may be our most influential hate group.
