Toadfrog said And also suppose (just for argument's sake) that the absence of missionary activity will condemn all those people to eternal damnation. Now, based on these assumptions, are missionaries "terrorists"?

You misconstrue. My complaint is merely rhetorical. I am pointing out that if anyone who disagrees with you regarding religion, particularly the "eternal damnation" stuff, accepts this premise (for the sake of argument) on the terms that you've stated above, they've lost the argument before they utter one word.
