When I moved into a rural county I learned very quickly that it was good manners to get to know folks for a few years before trying to bring my big city ideas into a functioning community. Then, after that few years, I learned that not only was it respectful and good manners, it was critical to understanding what relationships and systems were already in place that were not immediately obvious, and which served the community quite well, thank you very much.
Your comments seem to presume that communities of color & poor folk are inferiors, that they live at "the lowest common denominator", and that it's somehow racist to not expose them to "alternative worlds". That being polite and respectful is this mythical "soft bigotry of low expectations" thing. It's simply good manners, common courtesy, to build relationships with new neighbors for a bit before presuming your innovations are needed, welcomed, or an improvement. Get to know folks, understand what systems exist before presuming one knows best. Who the hell do I think I am, to have any kind of expectations of others when I am the newcomer?
I learned this in a white, rural, working class community that had it's share of second home rich folks, but that thrived as a farming & fishing community. After some years there, my desire to jump into community work was welcomed, because I took the time to weave myself into the existing community. That is what this article is about. Calling it racist is pure projection.
