I came across this video link from Las Vegas illusionist and entertainer Penn Jillette (of "Penn & Teller" fame). Apparently, after a performance, one of the "volunteers from the audience" from the from previous nights' show came up to him, complimented him for a great performance, and then gave him a copy of the New Testament. Penn is an outspoken atheist, yet for some reason was visibly moved by the sincerity of this gesture.
Penn's comments on his video blog can be found here: http://www.youtube.com/watch?v=7JHS8adO3hM. I found it very worth watching.
Here's a few comments from the actual blog.
"I've always said I don’t respect people who don't proselytize. I don't respect that at all. If you believe that there's a heaven and hell and people could be going to hell or not getting eternal life and you think 'It's not really worth telling them this, because it would make it socially awkward.'
And [I also don't respect] atheists who think that people shouldn't proselytize, [saying] 'just leave me alone, keep your religion to yourself.'
How much do you have to hate someone to not proselytize them? How much do you have to hate someone to believe that everlasting life is possible and not tell them that? If I believed beyond a shadow of doubt that a truck was bearing down on you, there’s a certain point where I tackle you.”
As I said, I found his comments (about five minutes) worth watching.
