I have traveled all over the world, seen a hundred different churches and religious beliefs, how they are all right and the others are wrong, or they are the only or in some cases, best path to salvation etc... Many of them will say I am a member of X religion due to god's or some other entities grace, when its really more because of their parents and culture. And before Tomas chimes in saying he is an exception, I grant that there are no absolute rules regarding children following their parents.
In my opinion though, INC is one of the worst I have encountered, simply because they are so closed and secretive, especially regarding finances. And they make to much of an effort at controlling the lives of their members, having every aspect of life revolve around the church, even going so far as to tell them who to vote for.
