"Making fun of born-again Christians is like hunting dairy cows with a high powered rifle and scope"

This quote by P. J. O'Rourke is an amusing way of stating that making fun of born-again Christians is an unneeded and excessive action. It resembles using a high powered rifle and scope to hunt dairy cows, which are animals that are not generally hunted. The quote suggests that born-again Christians are not a hazard and ought to not be dealt with as such. It suggests that teasing them is an overreaction and an unneeded use of force. The quote likewise implies that born-again Christians must be respected and not mocked. O'Rourke's quote is an amusing way of advising us to be respectful of those who have different beliefs than us.
