Did you read the article? I think it does a pretty good job of explaining what the author means by that phrase. The author articulates her concept of a “far center” (as opposed to far right and far left), which she describes as people who take liberal values to reactionary extremes, valuing civility over justice, etc.
The far center is for free speech and bourgeois institutions; it is against cancel culture, student protests, and radicalism of any kind. Yet it rejects the idea of a shared ideology or politics. Instead, its members see themselves as independently sane individuals — concerned citizens who wish only to defend civil society from the unbearable encroachments of politics. So the far center is liberal, in that its highest value is freedom; but it is also reactionary, in that its vision of freedom lacks any corresponding vision of justice.
Yeah, a good bit of the article is dedicated to pointing out that there are a whole swathe of public “intellectuals” who describe themselves as Liberals but are shallow and regressive in their actual ideas.
