Obviously, I still have work to do on that point.
Further, your definition of "what the comic is about" is also wrong. You seem to think it should be about me regurgitating an accurate portrayal of how the game should ideally be played. Nothing could be further from my mind. The comic is criticizing not how the game is intended to be played, but how the game is actually played and has been for 35+ years. And how it is actually played 9 times out of 10 is that goblins are slaughtered because they are goblins, and the book says that goblins are Evil so it's OK. If you've never played in a game with people like that, then congratulations! You've had an exceptionally lucky D&D career, and that whole portion of the comic's subtext is Not For You. But there are plenty of people who maybe have never given it a second thought. Just because you've already learned some of the lessons of a work of fiction does not mean that there's no point to including them.
Now, if you want to rail on me because the first time Redcloak walked on screen, I didn't know everything I would later write in Start of Darkness, go right ahead. It would be a grossly unfair criticism being that it's common knowledge that I started this comic strip with no idea that it was going to last more than a dozen strips, but at least it would be an accurate one instead of one built entirely on one's own personal biases about the D&D game and how I'm not reading your mind so that I might live up to them.
Oh, and I will continue to veer back and forth from obeying D&D conventions to ignoring them when and as I see fit, so if that's going to bug you, you should probably stop reading now. Because I simply do not care about the level of consistency that you seem to find important.
