Well, there's freedom and there's liberty. We often use the former to include the latter, but they're completely different. We only have the freedom to do the right thing. We are not free to do evil things. We may have the liberty to do them, of course. Now in a liberal society like the US, we are at liberty to do many things we ought not which is partly motivated by either skepticism on the one hand and a wish to maintain the peace on the other because enforcing certain behaviors would actually result in an even worse status quo (there's a hint: make it uneconomical to suppress certain freedoms). So no perfect liberality exists nor could it. The question of which liberties ought to be tolerated is answered by our constitutions, but even those are bounded in practice. You have blasphemy laws and you have hate speech laws, both of which constrain speech. Now, I don't think which are in force is arbitrary or that it's all the same or relative--tyranny has an objective standard and not suppression of what I happen to want to do--but the fact that we always have had them is proof that freedom (liberty) of speech is always limited.
To your point, the proper way to characterize the current status quo is that a certain kind of leftist orthodoxy or ethos has come to dominate institutions, organizations, and corporations that otherwise pretend to some kind of "neutrality" in ways that don't actually obtain. So what you have is a religious war of sorts and this leftist religion currently has the upper hand. As a result, laws that constrain liberties along traditional lines have been eliminated over the course of the last century, replaced with new ones reflecting leftist norms. What irks me most is the mendacity. At least confessional states give you the courtesy of telling you they're confessional. You can work with that even if the confession is wrong and at least everyone's clear about the circumstances you're in instead of living in a fog of lies. But lying about ideological orientation, also while knowing fully well others disagree with it, is dishonest. But people are noticing. (As people are booted off YouTube and Twitter by an increasingly severe leftist standard, a new market opens up for alternative services. Of course, that doesn't quite extend as nicely to laws. We might have to begin to have to resort to samizdats.)
