In the publishing world, resignation is the polite term for being fired. And I disagree with your view of cultural appropriation. If it is taken and commodified for the public at large, the authentic culture is lost. WP Kinsella's cartoon characters may be funny to some, but it's a misrepresentation of indigenous people. If you're not willing to recognize how native culture has been undermined by government, church, and private racism, then you're not likely to listen to reason.
