These first two sentences indicates how much you are 'over protesting' about protesting!
The government proscribed a protest group that was protesting on behalf of a terrorist group who were dedicated to 'Action' ...it is in their name for goodness sake. The 'action' it chose was to invade military areas and damage military equipment and was correctly categorised as terrorist actions.
Subsequent demonstrations which supported the proscribed group, (which admits it committed acts of terror, but it was apparently 'only a little bit terrorising') involved a kid with a 'piss-take' banner, ' who was initially arrested (for 5 mins) incorrectly, then released.
'Me, thinks you protest too much'!
Moreover, Britain has had no authority in or over Palestine since the late 1940's. When it did via the Palestine Police (British} lost 141 service people and had 475 wounded/injury in this period through trying to contain the terror activities of Irgun, Lehi (Stern Gang) and temporarily Haganah.
Britain now has no responsibility or authority or duty to be involved and should not seek to be involved in Palestine.
* On a personal note
An uncle of mine served in the Palestine police 1945-47, he was wounded twice, the second time requiring his discharge and he carried a limp which he retained for the rest of his life.
His generation paid Britain's price for trying to keep two warring parties at bay, two people's who are to this day still at each others throat.
If my uncle where still here I know would say to the government of the UK... "stay well out of it".
"Methinks" , as I said before, you'd have the suffragettes in jail for decades. Of course you'd think that proscribing Palestine Action as a terrorist group was totally fine.
You're also just making stuff up regarding anyone in Palestinian Action "admit(ting) (they) committed acts of terror". I assume that you're referring to the Brize Norton incident, the embarrassment of which is the trigger for the the terrorism proscription, despite RAF engineers stating the spray paint administered would "not affect operations". Or maybe the Filton Elbit incident, when the defendants, despite not being allowed to provide context for their actions in court (and their barrister being charged with contempt of court for doing so when summing up), were tried on standard charges and their sentences then subsequently being increased due to "terrorist connections"? Or are you referring to the hundreds of citizens arrested for holding placards, being charged under perverse application of terrorist laws, as a consequence of direct inappropriate proscription rather than just charging the culprits of the above crimes under pre-existing laws?
What is the point of your mystifying digression into Britain's authority over Palestine in the 1940s? Do you think anyone protesting is expecting Britain to be militarily involved or are labouring under the illusion that we retain any jurisdiction in Palestine? People, in fact, have been protesting against our logistical support and arms exports for and to Israel. Which is very much in the capacity of Government to influence, as would sections against the state of Israel be. We're not, as your uncle might have stated, "stay(ing) well out of it".
To be clear, but you know this, many ordinary and brave people are now protesting the Government's decision to proscribe Palestine Action precisely because it is a transparent authoritarian over-reach. You seem to be ok with this, but I don't for a second believe that you're not cognisant of the wider ramifications of this decision and the precedent it has set ,nor the further issues caused by the current proposals to ban repeat protests. Whether you agree with the cause, or the actions of this particular group, the application of the Terrorism Act in this case should be of concern to all citizens of this country, as well as being a nightmare to police even without Plasticine Action "piss-take banner(s)". The fact that Palestine Action was proscribed in the same act as Neo-Nazi groups (including the snappily titled "Maniacs Murder Cult), and joins an illustrious list including Al Qa'ida and the Wagner Group, is as chilling as it is egregious and it is notable that we don't have octogenarians being nicked for holding cardboard stating "I support the Maniacs Murder Cult". There's a reason for that, and it is very obvious.
