First, it's hardly MY idea, in as much as 2000 years of Church history and the great majority of Christian churches, both Catholic and Protestant, oppose the innovations of the anabaptist wing of the Reformation whose followers practiced REbaptism (where's that to be found in scripture?).
That movement's spiritual descendants today will also baptize 8 year olds, 10 year olds, or children in their early teens, pretending, as they do, that such candidates are de facto adults.
Find ANY OF THAT described in Scripture and we can continue.
