Another backer of the game since eons ago, and just browsing because of a BSOD while playing the game. And then I ran across this thread....
At first I thought that one insignificant dumb tombstone limerick could be removed from the game without too much of a problem -- I always default to wanting to please and get approval from others -- but after reading Fynnding's awesome reply I really hope that Obsidian doesn't encourage those who use manufactured outrage like this to silence creativity. I also took time to listen to a Soundcloud recording from TotalBiscuit who argues eloquently for the freedom of developers, and who raises some good points in rebuttal.
In the end those who are complaining may feel outraged, and for that I do want to help them, but they have ownership of their emotions, not anyone else. Removing this one low-brow humourous tombstone won't solve their issues with the world around them or keep them safe from their own phobias, unfortunately.
