I don't draw webcomics and the idea would probably be too wordy, but the thought was something along the lines of:
a young girl, hands on hips, glaring at a table full of secretive lurking geeky boys playing D&D. "Let me get this straight. You're playing a loincloth barbarian with muscles the size of basketballs, you're playing a tree-hugging elf who talks to squirrels, and you're playing a female assassin with pure black skin who's naked all the time... but you won't let me play a fairy because it's "unrealistic"?"
(basically, thinking about how uncomfortable some people are at the idea of getting "cute" fantasy into their... also fantasy.)
