Alright, first off, I would suggest doing some research. Then, after doing this research, talk to your parents about how you feel in an eloquent, educated fashion.

As an aside, I would like to say that you are absolutely correct. Religion is bullshit. I have researched the topic extensively and have written many papers on it. Religion is, without a doubt, a major problem and needs to be stopped. Throughout history, religion has been the leading cause of death. Unfortunately, until people start thinking logically and get away from their sheep-like nature, it is here to stay; and until that magical day when everyone reaches this major epiphany in their lives arrives, we just have to deal with it on a personal basis.
