I think in order to clearly define whether the man is a "racist", one would have to clearly understand that black people, including the black middle and upper class, are very dissatisfied with their treatment at the hands of the white power structure.
You'd have to clearly understand the issues involved; they have very good reasons to be angry and to demand change.
If you're white, you're only going to understand these things through earnest and careful reading and research, because these aren't things that white people know about, for the most part. Our entire, white-run, patriarchal society is structured to shelter us from having to know about them, so that we can enjoy our lives and not have to recognize our privilege, which would in many cases detract from that enjoyment.
Reverend Wright is responding to the feelings of his congregation, and addressing their needs, physical, spiritual, and emotional.
That's what a church community is for.
If it didn't do that- offer solace and solutions to problems that are all too real and seemingly insurmountable, if it didn't offer hope, then people simply would not go.
The needs of black parishioners in black churches are different from the needs of white parishioners in white churches, because white people made it so.
We structured society so that we would have privilege at the expense of a disadvantaged minority underclass, and Reverend Wright simply attempts to minister to their needs.
If you don't like it, learn about the issues and start working to change them.
The immediate way you can help equalize things is by voting for Barack Obama.
