> It is difficult for someone that is not part of a minority to spearhead efforts to outreach to one, because they don't experience the same issues. Literally, they don't have the right experience for the job.

We've invented tools to deal with this: language and literature. Almost everyone has experienced some form of discrimination, even if for many it is only occasional and minor, and that's enough to give a good writer an opening to get inside the reader's head and use that to build upon and paint a vivid picture of the more frequent or major discrimination the writer has dealt with.
