There are a lot of people who fundamentally believe in the tenets of classical liberalism, just not very explicitly or strongly. Making it safe for them to express their attitudes is important.

There are also a smaller number of believers in at least the majority of classical liberalism because either they directly have strong feelings that it is a superior system, or through an examination of history and/or human psychology have concluded that it is, while perhaps imperfect, a heck of a lot better of a way to organize a human society than anything else on offer.

That there are also people who wrap themselves in the language of liberalism while advocating for illiberal measures (both on the left, where they tend to adopt the rhetoric of rationality regardless of whether they follow it, and the right, where they tend to adopt the rhetoric of free speech regardless of whether they follow it) in no way demonstrates that there is no support for actual classical liberalism. Indeed, it demonstrates that the support is so strong that few are really prepared to tackle it head-on.

Now, whether TaraElla actually manages to reach enough actual classically-liberally-minded people is, of course, open to question. But there exists a receptive audience of good faith and noticeable weight; it's solely a problem of distribution to get it to that audience.
