I think you and I are saying the same thing. Apologetics are directed at current Christians who are on the fence and need an intellectual justification to stay.
"On the fence" is too strong a phrase for this situation, I think. They don't consume apologetics to push themselves back in, but rather to keep themselves completely immersed in the religion.
Nope, I'm speaking from personal experience with myself and others: apologetics is to keep those on the fence from jumping over entirely, and it does often work.
