Honestly get used to it, there is a vast untouched market out there in terms of younger folk. D&D has been in the last few decades purged of most of it's 'mature' content for this reason. My oldest daughter was praised by her 1st grade teacher a few years ago because we let her play D&D. It is now less viewed as a tool of devil worship and all that other crap and more as a math and social building tool. The more success that is seen of that nature the more it will spread. I personally don't see an issue with this, the more people playing the better is my feeling on the matter. I don't play this game for 'mature' content, its a fucking over blown game of plastic army men. If they suddenly purged all the fluff and models of anything 'mature' I still would play the game, it would not reduce my enjoyment or desire to play one bit.
