Going after coreligionists of the offenders would make no more sense than bombing the Vatican in response to an IRA attack. The actual culprits of the Paris attack could have been shot dead in the act with minimal difficulty, except that the victims were victims of terrorism twice over — the first time when their government made it impossible for them to go armed for self-defense.
So the solution is two-fold: military action against the command and control of the terrorists and, as importantly, elimination of the laws that disarm French civilians for the convenience of the terrorists. I am not holding my breath on that one, though several East European countries made defensive carry a reality after escaping from Communism. Perhaps people have to hit rock bottom before they consider making freedom legal again.
For the record, I’ve trained several Americans in the use of firearms for defense. Them being Muslim was entirely irrelevant to the process. Like many, they came to America for the benefits of legally secular, egalitarian society and have no interest in changing it. They are, as far as I can tell, the majority in America. In certain other countries, we have no idea what the majority thinks, as the general population is hostage to violent and insane rulers who control not only the expression of opinions but also, through schooling, the formation of opinions.
