Labour knew Palestine Action posed no violent threat, but banned it anyway amid lobby pressure

Spray painting a few planes is an EXTREMELY measured response to your government participating in a genocide IMO.

The government response is eerily similar to how the IDF reacts to anything resembling resistance in Palestine when it comes to proportionality.

They didn't "have" to do anything; both the ban and the UK's continued participation in the genocide are active unforced choices the government made. In the first place a law making "I support X" a crime has no place in a free country, no matter what X is. Yes, even the really bad thing you just thought of right now. Using such a law to crack down on anti-genocide dissent is nothing short of tyranny.
