I bet attacks like these will increase in the years ahead, since France will become 10.9% Muslim by 2050. (http://www.telegraph.co.uk/news/worldnews/11518702/Mapped-Wh...)
In 2015, it's probably more linked with the foreign affairs and military operations.
Maybe if you stumble onto some of these terrorists in Paris now, you can inform them that their cause is just oh-so démodé? You can let us know how that works out.
Usually, I'd argue your point but.. today, I don't want to, my country was attacked and I feel horrible already. This is neither the time nor the place. It doesn't matter where they're from, I hope each and every one of those fuckers get caught, and I truly hope this is the last comment like this I'll see today. Unfortunately I know it won't be.
Keep this xenophobia to yourself.
Crystallizing on the fact that every terrorists are muslims is like saying that most serial killers are on average 1m75 and each pedophile have one left foot and one right foot.
