What a horribly sad way to live your life. People are no addiction, they're a necessary (and awesome) part of life. Regardless of your spiritual bent: Athiesm - We evolved from social primates into other social primates. You're adding a lot of psychological stress at a fundamental level when you don't live the way you're bred. Christianity/Judaism - God made us for community. "It is not good for Man to be alone". Bud…
Also, your argument implies that every atheist views sex-change operation as necessarily bad, since they're a fundamental modification to "the way you're bred". This is certainly not true.
I find your argument uncompelling.
*Not to be confused with faith.
