It reminds me of another great quote: "You can't tell which way a train is going by looking at the tracks."

I think your quote says nothing about my belief in Christianity, others' beliefs in other religions, or others' lack of belief. You seriously underestimate religion and atheism to apply it anywhere.

"It is easier to fool someone than to convince them that they've been fooled." What does that saying mean to you in the context of your belief in Christianity, others' beliefs in other religions, and/or others' lack of belief in all major religions?
