Nothing too profound here, just a practical observation.

To god-botherers, Buddhism is spiritual kryptonite. If said with a calm and sufficiently level gaze, the phrase "I'm a Buddhist" sends them wilting away.

In the rare event that they persist, an attitude of compassionate vaugness will quickly melt them. "Do you believe in Jesus?" "Just exactly as I believe in you" It's particularly effective if you can arrange your face as if you were watching a puppy chew on a toy.

To my way of thinking, my actual spiritual beliefs are none of their business - the purpose is to quickly and calmly shut down the conversation.
