So yes, to get over the obvious, murder is evil and civilians who have nothing to do with their governments’ policies do not deserve to die because of things that their governments do in other countries.
Nevertheless, the French government is heavily involved in bombing Muslim countries. That doesn’t make what happened any less murderous, but France’s government should stop doing that if they want to take away an obvious motivation for Muslim criminals to murder civilians in their territory.
Challengers of this assertion must ask themselves one serious question. Why don’t Muslims ever attack Switzerland?
(Shhh, come close and I’ll tell you…it’s because Switzerland is neutral and doesn’t go around bombing other countries.)
