Is there any merit to Disney animation bias, or just whining over imagined bias?

Do you see any animation discrimination as the author of this article alludes? But let’s entertain that Disney use the animation difficulty as an excuse to keep their female heroines pretty, cute, and attractive as oppose to homely, plain, and unattractive, would not that be good business for them? I suspect girls pretend or make believe they are Disney heroines more than boys do the same for male Disney princes or heroes. From what I know, no girls wants to be plain, homely and unattractive so why would they want to make believe they are that, even by way of a persona of a homely Disney character? If Ariel, Rapunzel, or Silvermist was homely would many girls want their costume at Halloween or if Vidia and Tinkerbell were unattractive would girls want to by their pajamas? I am sure they could have gone like Pixar and had characters like Colette (Ratatouille) whom many fans do not like because she is rather plain, and some would say ugly. I don’t know it if it just another thing to whine about, but as far as business goes, I would not expect them to do it different.
