Does that go for liberal or philosophical ideals like free speech?

I come across a bit of rhetoric identifying free speech as a right-wing authoritarian cause, arguing that they "claim, twist, poison, ruin" it, so it's fine to give it up and no longer defend it.

Those rhetoricians seem to have a skewed or ahistorical disregard for the advances in political philosophy from the enlightenment era that got society out of the dark ages, away from authoritarianism & toward political plurality & liberal democracy. Freedom of speech was a foundational development & its growth enabled the civil rights movements that followed.

Yet according to the rhetoric, it's a problem now that right-wing authoritarians claim it as part of their cause. They'll just let them claim & define it, and now that free speech is wrong (since they let right-wingers "have" it), it's okay to limit & undermine it.

One might think they're right-wing authoritarians in disguise trying to dupe everyone into threatening the foundations of liberal society. Whether or not they are, there's a good chance they'll show up here possibly in response to this comment.

Is there a name for that type of rhetoric or the people who argue it?

Anyway, it all seems like capitulation to me. I think letting fascists claim such philosophical ideals is a mistake.
