A friend of mine tried to get into it, not because she really wanted to, but because she was really curious. She got a couple steps into the initial whatever you have to do before she doubled back and said 'ha, that was dumb'
I've only known a couple scientologists personally, they all fervently defend it and talk about how much it's helped their lives and made them better people.
From what I understand, low-level scientology incorporates a lot of therapeutic psychology into its shtick, which, if you have a shitty ass life that isn't together, will most likely help you out in some way, beyond that though, it seems the further down the rabbit hole you get the more twisted and weird it all becomes.
Funny story about it though, well sort of funny. Back when I was living in boston, 2 friends of a friend came in from chicago and visited our apartment. These were two stoner kids and they naturally wanted to smoke out, my roommate, also something of a stoner, treated them to our hookah(I don't smoke anything anymore) They had never smoked hookah before and treated like a bong or a pipe... bad idea, they got incredibly off the walls super high.
So, in their inebriated state, my roommate and their friend(my friend) decided to fuck with them. They made them watch this psychedelic video and said it was a scientology initiation rite and that they had to watch it 4 times before they could get to the next step.
The kids were totally freaking out, paranoid and stuff, but they were too high to do anything about it really. So they watched the video FOUR TIMES. During with my roommate went to his room and got out this traditional indian robe he had, put it on and started saying all this random whacky philosophy stuff(he's a big philosophy buff)
The whole time I was in my room, occasionally coming out to assure the kids that my roommates were serious, and that resistance was futile.
Finally, my roommate drove the kids to the place they were staying. It was like 3 AM by then and instead of driving there, he drove around aimlessly for about an hour continuing the scientology prank. Finally he parked and let them out at a scientology center a couple blocks from where they were staying!
Pretty cruel yes, but funny as hell too.
