My Religion

So I've never really mentioned my religion but I think it may be necessary if I'm going to say the things that I believe in. I am a Christian. I do believe in speaking in tongues I do believe in the Holy Spirit. I have my own beliefs some from things I have experienced some from observing other people, some from my church. I also have some doubts not in God but in religion. Its is too holy sometimes. I mean its not okay for me to drink beer but I can drink wine??? WTF? How is that possible? And don't give me that crap about Jesus drank wine, they drank wine because water conditions back then weren't that favorable. His equivalent of wine in modern times is like our bottle water with flavor. Anyway I digress onto my main beef. Where in the bible does it say I can't use the words you ppl classify as profanity such as..D&#n, B*$@h, A$$. These words aren't always profanity. B*$@h is used to distinguish a female dog from a male. A$$ is used to speak of a donkey. D&#n describes being cursed. It even says in the bible eternal damnation so what the H--l? Can someone pls explain why I can't use these words or their friendly counterparts (darn, witch, butt, etc)?
