Very few parents are "enlightened" and allow their children complete freedom to choose their own religion - particularily as teenagers.
That, and the rest of this thread, is a good case against "child" (including teenager) baptism, IMO. (See? I do have some ...) I would absolutely croak if my son asked me if he could MARRY at age 12 or 13; and we're told making a dedication to God is the MOST serious decision one can make, yet we're asking (and allowing) the above-mentioned confused, hormonal, rebelliously-inclined ... CLUELESS teenagers (and younger) to make that decision? Then - bear the inevitable consequences (for many/most) of that decision when the "foolishness in the heart of a boy" and that "bloom of youth" thing kicks in.
