why do Christian and Muslims laugh at scientology?

i was asking one Christian they said "it's made up and fake" i was thinking what Christianity then ?

People laugh at things they don't understand.

Aliens from outer space is just ridicules. A guy who rises from the dead and a flying horse...now this I get

They really do have the right to laugh. There is actual evidence - from the founder of the religion no less, that it was a made up religion for profit. (Notes from L. Ron Hubbard to his wife)
Its proved to be bullshit, definitively; so they can laugh.

Come on, the person who made the religion wrote sci-fie novels.

They laugh due to a failure to recognize a "pot calling kettle" situation.

Christianity and Islam are 'accepted' by society due to a pervasive "appeal to tradition" fallacy. If Christianity had not existed for the past 2 MilenaIAr so, and then someone published the Bible today, it would likely be considered just as nonsensical and unbelievable.

However, for them to admit that would require them to drop their carefully-constructed shield of religious superiority masquerading as holy humbleness.

Scientology is like worship ping the stuff that happens in Mass Effect.
No wonder they laugh...

they don't laugh at it. and i know christian scientists.

Because the organization of Scientology is ridiculous and corrupt...in Europe their leader of some sort was under arrest for taking bribes or something stupid..

Laugh? I don't think laugh is the appropriate word.

Scientology is simply a fad. To think it's something new is ludicrous. There is nothing new under the sun.

Is very strange, but I have not see any person laugh me about Scientology ... maybe because I'm Scientologist, I have found some persons that only have read some "news" o "wiped"DOAd i have found that really they don't know what actually Scientology is, and when they ask me, I give then right answers; with curiously make sense to them.

Also when they see the original web site of Scientology, or read some books, some start be a bit in confusion ... because they was thinking that Scientology was "something else".
