In defense of the UK government, they didn't ban protesting the genocide in Palestine, they banned expressing support for a specific organisation which protested the genocide in Palestine by breaking into a military base and damaging equipment. It's an important distinction, and to claim otherwise is spreading misinformation.

That said, this ban is very short sighted and seems out of touch, I expect it'll just create a social divide between those who find a way around it and those who don't, which may be worse than the problem they're trying to solve.
