I'm going to make a BIG assumption here that you are a teenager, likely living at home.
It is so normal at your age to start developing your ideas and ideals, separate from your parents. This is part of the glorious process to maturity. In my opinion this development is suppressed somewhat by the society, by its insistence that everyone believes the same. It is good to pause and question.
Due to the extreme consequences of expressing indepedent views in a Witness home, I strongly suggest you keep those to yourself until you are moved out from home (hopefully in a college dorm, further developing your independence). You can always ask questions of your parents, as long as they are along the lines of "What do you think about....?"
If you haven't committed to baptism yet, try and beg off until you are an adult. There is so much resposibility and consequences attached to baptism.
