just read this great topic you started. Personally, having grown up in a fundamentalist enviornment, this desire for the apocalypse seems to based upon what these "christians" (Christian means Christ-like & followers of hate are not Christ-like in my opinion) see as "judgement against evil" & being somehow rewarded by God by staying "true" to Biblical teachings. They consider it, strangely, a form of love: convert others so they will not perish. However, having been in such an enviornment: to quote Tina Turner, "what's love got to do with it?" (LOL - couldn't resist a little joke there).
Perhaps this strange desire for the world to end is also tied to the dualistic mindset of these believers. Unfortunantly, apocalyptic views have been around for a long time, and at least since Zorastorism in Ancient Persia.
Viewing those who are not as "true believers," they are looked upon as "evil," which is very sad.
In regards to the means of trying to make the apocalypse happen, it is not only apart of radical Christianity. The Moonies, I think, tried to make it happen in Japan in the 90s. Of course, other examples are the Davidians & the Jonestown Movement, which all equaled tragically. Well, I have babeled on, but yes I agree w/ all of you: Christian apocalyptic beliefs are dangerous.
