Please don't protest against Israel's Genocide

For reference:
Starmer urges students not to protest on 7 October
One of the more bizarro stances of a government filled with many of them.

I fully agree with Starmer.
Yes, there has been a Genocide in Gaza. Yes, there is an ongoing genocide, but the British Public do not have free speech and Starmer is our leader.
Yes, women have been assaulted, violated, and tortured:

But we should be silent.
Do not protest.
