“Ones religion is not the issue.â
Muslim terrorism is performed specifically to advance Islam across the world, sometimes masked as a retaliation for something done to Muslims in the past.
I can only think of one case where a terror act was committed specifically because of Christian ideals, and that would be Erik Rudolph.
A Christian might commit a terror act, but usually not in the very name of Christianity. A Muslim will commit an act of terror because someone else is not following Islam (Ikea beheading), has insulted Islam or Mohammed (Charlie Hebdo), or because some non-Muslim harmed a Muslim somewhere sometime (Boston Marathon bombing, Madrid bombings).
So it does make a difference.
RFK was killed by a Rosicrucian (!) but he did not act in the name of that religion.
And even if said 'Christian' committed a murderous act in the name of Christianity - he would be unable to point to the Scripture that justified his act.
The problem with Islam is that the 9/11 Bombers, and every other Al Queda, or ISIS, terrorist can point to the surahs in their books that justify their actions.
That is the big problem and difference.
