Are you old enough to get a driver's licence? No.
Are you old enough to vote? No.
Are you old enough to open a bank account without needing your parents to co-sign for you? Probably not.
Are you old enough to get married without your parents' permission? No.
Are you old enough to join the military? No.
Are you old enough to sign a contract? No.
Are you old enough to get a job? Maybe, but maybe not.
My point is this: The law of the land does not permit *children* to undertake certain adult activities, and for a very good reason: a child's power of reasoning and critical thinking is not fully developed. Unscrupulous people prey on young people like yourself and trap them in situations that can cause irreparable damage to the young person. Why do you think so many kids start smoking or trying drugs when they are teenagers? It's because they really want to be accepted by peers, despite what they have been taught about the dangers of these behaviours.
If the Watchtower Society had your best interests at heart, why would they need to put so much pressure on young people to forego higher education, or limit association outside the Congregation™, or get Baptized™ before they are old enough to really truly understand the consequences of being Baptized™?
If your parents are reasonable, they would allow you to complete your high school education in a Public School. If they are reasonable, they will allow you to wait to get Baptized™ until you are an adult (like Jesus did). If they are reasonable, they will allow you to go to community college or vocational school to learn a trade so that you can support yourself if and when you wish to Pioneer™ (like the Apostle Paul did). The Bible™ says that "overseers" should be "reasonable" (1 Timothy 3:1-3) and that Christians should "let your reasonableness become known to all men" (Philippians 4:5).
Only people (and Organizations™) who are unreasonable would try to force a person who is not legally an adult, to make adult-sized commitments. If someone was trying to get you to sign a contract or force you to get married or recruit you into a gang at your age, they would be committing an illegal act. I believe in my heart of hearts that coercing or strongly persuading or using threats to get children to commit to a religion should be punishable by law, particularly if leaving that religion in adulthood results in severe negative consequences for that person.
PLEASE WAIT. Peer pressure is still peer pressure, whether it's from kids at school or kids at the KH or even family members. You DON'T HAVE TO DO THIS.
