So it's the addition of visible effort NOT to indulge in stereotypes, etc?

On that point I can agree, but sometimes art is just art... It's a reflection of what's in someone's brain. If what's in their brain is flawed in some way, such as them being racist/whateverist/having offensive views, that'll come through. It doesn't make it right, and it certainly has all right to be criticised, but it also shouldn't be quashed and left beuried in the ol' noggin, I think.
