No, it is not. You know so little about this that it's laughable. The xenu thing is a trifle in the scope of Scientology, except for morons like you.
If I am wrong, tell us what Scientology is trying to "fix"? We know what Christianity is trying to fix: we are all sinners, Jesus paid the price for that. That's what is wrong with all of us, we are sinners. What is wrong with all of us according to Scientology? Hint...it's the thetan bullshit.
