Yes the dubs are going crazy with joy at the thought of the 1000's being killed and having their lives destoryed by the earthquake/ tunsmai.
I'm not and I am still "in" at the moment and I know of many genuine JW's that wont be going crazy. However, these occurrences will cause some to question if there is an increase.
