Well the UK military is being used to support Israel so, fair game. This isn't about the people who did that though, it's a direct attack on freedom of speech. These people are literally about to be arrested for saying the "wrong thing".
Sorry, when protesters shout "Free Palestine", "Long Live October the 7th", "From The River To The Sea..." (I'm not even going to repeat that in full here), I can't put it other than there's a bunch of neonazis trying to be on the wrong side of history (again).
There is absolutely nothing wrong with any of those statements. Israel is an illegitimate state, worse than Nazi Germany. It should not exist and Palestinians have every right to self defense. None of that is relevant to the UK though, they're clearly occupied by the zionists since they've made it illegal to stand against a foreign terrorist colony.
Also, most people on this planet are anti-Zionist. The "wrong side of history" will clearly be Zionism, as dictated by all of us.
They already arrest people for showing support for Palestine Action, which is why you get the unedifying spectacle of cops carrying little old ladies into vans and carting them off.
If Palestine Action didn't attack RAF Brize Norton they wouldn't have been proscribed.
There is a big difference between activism and directly harming national security interests.
