As an exercise in missing the point and doing so in a pompous manner, I give you an A+ here. Da Iawn.
Quite clearly it's not about the exact cost which runs into millions. I've seen several figures; £7m, £25m, £30m and £55m. None of which are acceptable. I suspect the Maniacs Murder Cult have cost us next to nothing and they are rightly proscribed too. Sharing an article that states £30m is not "parroting". If it is then I look forward to you making that claim consistently. Of course, you won't do this.
It's UK military hardware that a group are targeting to try and force political change. As I said, if you cant see how that can lead to a proscribed group then that surprises me. That said, I wouldn't be surprised in your case Cyril if you actually think you do know more than the MOD and UK govt lawyers!
They broke in and caused serious damage to UK military planes cos of Palestine. They showed no indication of a change in that policy. They got proscribed. Wholly agree with it or not, agree with the wider ideological position or not, it's not a complex thing to grasp and that's my essential point.
