Say it isn't so;
From her blog:

Many Caucasian women AND men in the business specifically request not to work in the "interracial market" and if you read some of the adult industry forums like www.xxxporntalk.com you'll start to see pretty quickly that many Caucasian performers, directors, studio owners, etc have a very negative view and outlook on African-Americans - I personally feel this mentiality has nothing to do with my ethnicity's "sexual or hygienic practices", but that this negative out lash has more to do with the attacker's feeling of self inadequacy.

It's actually very disappointing to learn that many agent's feel their Caucasian performer's value will "go down" by him or her working with African-Americans. I suppose this way of thinking has been a primary factor as to why I will be very rarely (if ever) shooting any adult scenes for any other website or DVD with the exceptions of those I put out independently.
