Madrid Bombings

At a certain level, if only we cared to step back and take a look at the big picture, as we philosophers are wont to do, it doesn't matter who were responsible for the bombings.

The questions we should address ourselves are:

What is this disease that the bombings are but a symptom?

Why does our Society marginalise and alienate a minority to the extent that they have to resort to anarchy, violence and terrorism to be heard?

Do they speak in voices of dissent in a Society that does not accommodate dissent within their so-called democratic process?
