Lemay was a wonderful writer - 8 Years in Another World was truly engrossing - so since he was happy to take the spotlight, while Rauch was a less wordy figure (his grudge-holding and malice were rarely spoken of in his own voice), he is more likely to get the blame. I also think some of the blame comes from AW falling apart at the end of his tenure and never really recovering, although he and Rauch were probably something of an anomaly in terms of stability (there's a thread buried on here with a title like - "AW - longest transition ever?")
I think the other problem is that many fans took his word as gospel, because so little footage of his era is available. What he said about the cast, especially Courtney, became fact.
The most revealing anecdote about his biases is probably when he takes time to eviscerate Val Dufour for stealing the spotlight from Susan Sullivan by being too hammy in the confession scenes that he wrote to showcase her. Dufour had been fired, and those were his last scenes. Sullivan was one of the show's leading ladies, and had plenty of story ahead. Yet the thrust of the story is that he was selfish, in the wrong.
I am sorry he never got to make much of an impact in daytime after that, and that his second headwriting run, which was excellent from the little we saw of it, was quickly ended.
Speaking of his ATWT consulting, he had a TV Guide interview a year or two after his second consultancy (which had been around 1994 or 1995 I think). I mainly remember it for his criticizing ATWT for becoming too out of touch with reality - he said during his time there he pointed out to them that three different characters had private jets.
