Flowerpower, an 11-14 year old isn't an adult and rarely knows what they're going to think in a single year, much less for the rest of their lives. The law protects them from signing contracts, etc, because of this. So no one born in and baptized so young can POSSIBLY be held accountable and then punished for learning or believing differently later.
But I do agree with what you said here:
I think some peopl baptist without reallt knowing what is in the bible and that your are also dedicate yourself to an organisation
