I know the types of posts you mean all too well.
The writer begins the post by stating how they cannot put their current feelings into words. Then, in a few sentences, they will do exactly that by describing how they are feeling. If the post is about something positive, you will typically see the writer claiming that they are "beyond grateful" for whatever event precipitating. If the post instead concerns a negative event, you will instead see the writer saying how they "cannot fathom" that the event is occurring or has occurred. This statement will then be followed by the writer saying something to show just how empathetic they are.
The latter part of the post would be a bit more preachy, consisting of several short sentences that all begin in the same manner and serve little rhetorical value, for example: "This is what the patriarchy looks like. It's the policing of women's bodies. It's the destruction of a woman's right to choose. It's the unmasked sexism of the Republican party."
These posts typically conclude with some sort of call to action, whether it be a reason why you should care or a link to somewhere you can donate money too.
Whatever is Anna's intention, this post just reads just like all the others of its kind, coming off insincere and contrived.
