as controlling as JWs are there is no f'kin comparison to Jonestown and trying to put them in the same boat is slightly offensive and plain wrong.
I don't think it's offensive to compare them to Jonestown, but I do think that there are some big differences between the two and comparing JWs to Jonestown is probably wrong.
What is similar is the cult mentality and the constant indoctrination. What is not similar is that the JWs are not "destructive" as the word is used to describe both Jonestown and the Branch Davidians.
While I agree that the JWs are a cult, I don't see them ever being destructive to the point of a mass suicide. The leadership is not collectively as insane as Jones and they have too much to lose if they come across as too cultish or dangerous.
