Almost as bad as "I'll pray for you" is when you sneeze and some Christian says "Bless you," and then sits there expecting you to thank them. OK, I just had a normal bodily function and you want me to thank you for invoking superstition because of it. Next time I fart do you want to praise Jesus? Come to think of it, I have had someone exclaim "Jesus Christ!" after I floated one.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
