When Whites Led the NAACP
That's a poor analogy because the Autism Hub is not a major civil rights organization; it's just a group of blogs taking part in an exchange of ideas, information, and personal perspectives about autism and neurodiversity. What's more, even if we look only at the early years of the NAACP, when it had much less influence than it does today, the analogy still fails because the NAACP originally was led by whites.
It's a little-known fact that the NAACP, in its early years, was led and financed chiefly by Jews. This was not done out of a sinister desire to control blacks or a patronizing belief that blacks were incapable of speaking for themselves; rather, the Jews who got involved in the struggle for racial justice knew all too well that they, too, could easily fall victim to the popular ideology of Aryan supremacy. They understood that when society becomes more open and accepting of human differences, everyone's lives are safer.
Could the black founding members of the NAACP have done it all on their own, without the organizational, financial, and legal help from their Jewish allies? Yes, given enough time and enough support from their own community, they could have built an organization led exclusively by blacks. Considering the vicious social climate of that time, however, it's quite possible that in the interim, their entire race might have been lynched by the Ku Klux Klan or sterilized by the eugenicists, or some combination thereof. Both of those hate groups and their repulsive ideologies enjoyed widespread popularity throughout the United States a century ago and had supporters at the highest levels of government.
Fortunately, the black activists who were involved in founding the NAACP had more sense than to jeopardize the survival of their race for the sake of maintaining exclusivity. They made practical compromises and accepted help when they needed it. Eventually, capable black leaders took charge of the NAACP and went on to accomplish many successes in the civil rights era.
Demanding exclusive control of everything from the outset is not always the wisest course of action.
