Does atheism need be considered sacred, for defacing of an atheist ad to be considered desecration? I noticed this on my way home on the subway last night, and am actually surprised it's the first I've seen (considering the Athiest Bus ad campaign has been around since the middle of February).

Clearly atheism ads on pubic transit are a contentious issue.

This one had a black marker taken to it:

There's probably no god.

The posted paper reads:

"The most important thing in life is to do everything you do with the most love for others. It is not how much you do, but rather how much love you put into it that really counts."

Has anybody seen any other incidents of sign modification?

I think it's kind of cute. I didn't have my camera with me, so I took the pic using my Macbook. If you see any other vandalism, snap a pic and add it to the Flickr pool.
