You've miss his point entirely, I think, despite me now getting where you're coming from. It's less that he'd accept yuri if it were merely interesting. He likely falls into the camp of "shit written for the coom is inherently uninteresting," in which he is right. I think his point is more "yuri COULD be interesting if written with something in mind that is not coom." I'm sure people could make stories with dyke characters that do actually have substance. But the fact of the matter is, coom is uninteresting and also the main characters of Peripeteia are apparently straight.
