...then you have the mentality of a terrorist.
Terrorists believe all infidels should be killed. They characterize infidels as "all Westerners". Therefore if you believe all Muslims should be killed you have the same mentality of the terrorists.
The "jihad" or "war against terror", depending on your religion, don't end until this mentality changes. Religion doesn't kill people, people kill people. Stop the people, not the religion. And try to do it peacefully. If some government killed my father or uncle or brother, regardless of the reason, I would see that government as my enemy...forever. That chain of thinking doesn't stop until the killing stops.
why should we kill all Muslims or kill certain religious groups? Not all acts of terrorism are caused by one religion or other religious group, any religion does not teach people to commit acts of violence or even terrorism, so it would be wise if we not judge or blame what his religion, but on the perpetrators of such terrorism.
not all Muslims are terrorists, although there are some terrorists who are Muslims, there are also terrorists who are non-Muslim, but who is wrong is not their religion, the perpetrators of terrorism are wrong.
