You might personally think defence trumps all other things - I don't. Its clearly not unimportant (and I never suggested it was) but defence is, we're told, something we use to protect our way of life and our way of life includes not being called a terrorist for doing something which very obviously is not an act of terrorism.

All forms of protest are under a sustained attack in the UK right now and this is just another extension of that. Sabotaging reality to exert control over a populace is obviously a very much worse thing.
