The issue is never the issue; the issue is always the revolution.
Proving that the protestors can shut down the workings of higher education brings power to the revolution.
Shutting down the moral decay that has become the Met Gala, however, is counterrevolutionary, since moral decay weakens the society and makes it more vulnerable to the revolution, so the protestors there must be stopped.
Remember, to the left your worth is defined only by your usefulness to the revolution at any specific moment.
What the so-called left calls the revolution is actually a reset to hereditary feudalism demonstrated by North Korea, Cuba and even China.
