Totalitarian nightmares
Maybe that’s why I can’t get into thick libertarianism: it sounds like a totalitarian nightmare to me.
Yes, you got it, it’s just like that, except without the totalitarianism.
Getting criticized over the alleged social connotations of your word choice, in light of recent political history in America, is not “totalitarianism” by any conceivable stretch of the imagination. In real totalitarian states people are jailed or killed over the language that they use. Get a grip.
You may not like a particular practice, but there’s no need to use this kind of melodramatic language to describe it. Particularly not when the melodrama distorts the position that you actually intend to criticize. (There are no left libertarians who believe in government speech restrictions. If someone believes in that, they’re not a left libertarian, but rather something else.)
