You can very easily have a forum where you have a free exchange of ideas and opinions without allowing the slurs. Isn't the free exchange of ideas what you are looking for, or do you want a place where you can have a free exchange of ideas, AND call people any slur you feel like?

15 years ago at NWP, it was "edgy." Now its just embarrassing, and it has been coloring people's opinions of you, and your forum, negatively, yourself for years. Do yourself and us a favor and make the small change. We're adults now, let's act like it.
