Basically, the problem with labeling missionary activity as an evil is that it assumes, without stating, that the religion being taught is not a good in itself. And regardless of whether I personally think religion is good, that is an assumption many religious people do not accept. So that asking such people whether missionaries are "terrorists" is akin to trolling.

So I ask this. Just suppose it is true that missionary activities disrupt peoples' cultures and cause suffering on earth. 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"?
