Many roleplaying conventions hold charity auctions, which are often very strongly supported by the convention-goers.
Ogre Cave reports that Gen Con (a major roleplaying convention) raised over $17,000 at its annual charity auction, held in honour of (recently deceased) Gary Gygax.
Their chosen charity, Christian Children’s Fund (apparently a favorite of Gygax) learned that sales of Dungeons & Dragons materials were part of the auction and turned the money down.
Apparently saving children isn't really so important after all, if the money might have come from people who like to roll dice and make up stories.
Fisher House Foundation accepted the evil, tainted money, apparently without reservations. So far, the unstinting wrath of the almighty has failed to fall upon them, but obviously it's only a matter of time.
