Is it 'leftie' to describe the actions in Brussels as ideologically driven and part of an organised campaign? Pray tell, why you think so?
The root of all this goes back decades and further to the policies and actions of the West; specifically the US. The ideology is just a tag on to promote the cause of their hate of the West to the Islamic world. The actions of the West in the Middle East is the root of this and as the ME is predominately Muslim and it is these people who have been oppressed then it is this religion that has risen up against the western countries.
I'm not too sure that being organised is a unique thing that is a catalyst to causing extremes. The West is organised........ though mob rule and the crowd effect do play a part.
