I appreciated Greta's "Blah, blah, blah" speeches because they precisely captured the pervasive feeling of speechlessness, far better than my own impotent and sullen silences in this period. Greta had found a way not only of critiquing language but also of protecting language: she was mocking their words, and what happens to her words in their ears, but she was also saving her words for spaces where they still might matter, where they still can be married with principles and actions, where people are not merely performing for cameras.

XREF: Connects to ideas about performative activism and the gap between words and action — echoes critiques of virtue signaling and 'greenwashing' language.
