I suppose at the time converting heathens seemed like a good idea. Being raised an American, with a solid belief of religious freedom; I don’t think that kind of campaign would work here. Not being familiar with the popular belief in other countries, I can’t speculate about them. I can hope that they would have the same kind of acceptance and tolerance. Of course, a few countries pop to mind which don’t have this freedom. This ideology would seem so foreign to someone who has been raised in such a closed minded environment.
On the other hand, it may be appealing to many to live in an environment in which there is no confusion about what to believe in. Not being surrounded by different philosophies, and everyone believing in the same thing that you do. I would imagine that would leave little room for deep philosophical discussions. It would likely eliminate the discord of clashing opinions.
Of course, that all sounds boring to me!
