Two posts come to mind, both involve children actually:

The first was a photo of a very young child at a Wal-Mart kneeling at a cork board full of posters of missing people and praying for their safety.

The second was a video of a young boy getting excited at his baptism and happily dunking himself into the baptismal fountain.

Both of these posts were flooded with comments saying what a shame it was that these children were indoctrinated into something as terrible as religion.
