Perhaps, then, not taken seriously. Certainly not in the right way. Consider for example the article's reference to "identity politics". This is, essentially, the entirely reasonable idea that who you are shouldn't be determined entirely or principally by how society sees you, but rather by how you see yourself. The sort of people this article is complaining about would however both reject any societal role in determining your identity at all, and can perhaps even get incredibly uptight and offended if you don't instantly perceive their preferred identity.
Most, however, who believe that identity is about self-perception don't go that far. But then such people are less noticeable because they don't make such a fuss about it. Which group gets paid more attention, though? Loud and small, or quiet and large? Almost always, as in any field, the latter get lumped in with the former. What often happens then is that no-one in the "sensible" group gets taken particularly seriously, though, tainted by association.
On a separate point, exactly how many people have to stand up, freely, and speak out in mass media accessible to millions about how their voice has been stifled before they begin to notice the irony in this complaint? People are still free to say what they wish to, perhaps even freer than before. What they are *not* so free to do these days, is to speak without challenge.
