Conservatives increasingly emphasize freedom of speech, but are their arguments genuine? 'Though the attachment of some conservatives to freedom of speech is genuine, often reflecting Burkean elements of conservatism, I worry that conservative support for freedom of speech has weak foundations, many conservatives wielding the principle as a weapon against outgroups.'
I don't see how supporting freedom of speech can be a "weapon against outgroups". Perhaps he refers to incidents where censorship was sold under the wrong label, "War is Peace" bullshit has a long, bipartisan history after all.
Liberalism has freedom of speech as a core principle but liberals are now treated as hostile not only by conservatives but also the illiberal left.
