People who believe in the rapture are so smart, agreed?

I mean not only did they manage to get million of $ donations off the people who believe it during the run up to may 21st, they also set up a get out clause which enabled them to rake in more donations until October 21st. They are so smart! I mean they get money and people fear the rapture, if I didn't have any moral sense I would do the same too, it's just a shame that I am a Atheist and don't want to rip people off with fantasy.
