Personally, I don't really have a religon, but our Lord and Saviour Shrek brings me solace every night when i touch my onions. I cry the sweet tears of his love when I massage my onions, gently carressing my donkey while Lord Faquaad sucks me off.
And I'm not even a teenager, I'm 21 this year.
I don't even know, I used to consider myself a Satanist but I don't read the Satanic Bible or follow the Satanic Rules of the Earth anymore. I'm mostly just an atheist, I don't have as much interest in religion as much as I used to. I've come out of that awkward teenage phase where I'm discovering myself and instead, I've just let myself be without applying too many labels. Even my sexuality is questionable.
None. I'm an Atheist.
I am a practicing Roman Catholic. AKA I am a Roman Catholic that goes to church every week.
Catholic, myself. :)
Also, to reduce confusion:
Theists believe there IS a god (or gods).
Atheists believe there is NO god.
Agnostics don't know one way or another. (The word means "I don't know"!)
