That's also how it's always been.

But I don't really see how any of this counts as "taking action." I'm not criticizing Ocasio-Cortez here, she's not even seated yet. But simply speaking (in remarkably vague terms, if you listen to what she actually said) to a crowd of student protestors who themselves don't have a plan on the issue they're protesting --- that isn't action, it's pointless social media, theater for the people who are already on her side anyway.
