Why Are Organizations Afraid of Diversity?

The national professional Association for CPAs (AICPA) is reaching out to minority professional organizations to help increase the representation of Latinos and African Americans in the accounting field. Asian Americans make up 9.1% of accountants compared with 4.8% of the working population. In discussing the need for organizations to make a better effort of recruiting and developing additional minority candidates in this area, Ken Bouyer of Ernst & Young notes:

We’ve got to move the needle. Sometimes you’ve got to be an advocate for diversity and not be afraid of that. And I think the AICPA … can continue to have a loud voice on this issue, and I want them to continue to speak loudly and continue to push, continue to agitate.

My question – why would organizations be “afraid?”
