Racism?

I heard about this on the radio this morning. I don't get it. How is it racism to invite a respected author, who is a minority, to talk about international issues. Especially considering he didn't even end up speaking!

Among the plaintiffs' complaints was Lakeside's invitation to conservative commentator Dinesh D'Souza to speak as part of a distinguished lecture series.

After Sims and other faculty members and parents complained, the school in January rescinded the invitation to D'Souza, who has argued that the underachievement of African Americans has more to do with cultural attitudes and behaviors than with white racism.
