Sphinx Organization isn't Racist?

I appreciate Margaret A. Cassetto, Manager of Corporate Partnerships, for promptly responding to my legitimate concerns about the racist nature of the Sphinx Organization:

I would like to clarify your misconception that the Sphinx Organization’s programs are exclusively for Blacks and Latinos. The only program for which Black or Latino heritage is requisite is the Sphinx Competition for young Black and Latino string players. This represents only a small portion of the people served by the organization. (The competiiton awards 18 semi-finalists annually.) The hundreds upon hundreds of young people who benefit from free and low-cost music education and exposure to classical music are of all races and ethnicities. Young people from all backgrounds participate in Sphinx’s full-scholarship summer music academy and weekend music institute. Likewise, when Sphinx artists visit schools across the country, it is a diverse audience of students who benefit from educational residencies and workshops.

Why do I remain unconvinced? Consider the following, review the evidence, and come to your own conclusions and act accordingly:
