"the quality or type of products they make aren't what DAZ wants to promote." It has nothing to do with quality or type. It's a subjective decision based on anticipated sales volume.

Again, the crux is based on exclusions and the perceptions of exclusion and fairness. Nobody likes to be left out of anything. "It strikes me as weird when I see so many emotional responses over things that shouldn't have them." They're artists. Emotion is, um, always rampant.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
