Diggs' appearance Tuesday was intended to foster open debate and inquiry, said Daniel Brutocao, president of the Gonzaga chapter of College Republicans.

The speaker focused on homosexual promiscuity and asserted that "homosexuality is the result of a bad relationship with one's same-sex parent," said Rod Aminian, president of the gay and lesbian campus organization, Helping Educate Regarding Orientation, in an e-mail message.

Aminian's group had encouraged attendance and debate about the lecture - and he said he supported the university's handling of Diggs' appearance, which included limited publicity.

"The university did not want us to advertise because it was a controversial topic, but they permitted us to bring the speaker to campus," he told The Spokesman-Review newspaper. "We acceded to their wishes in this matter."

In 2000 and 2001, Spitzer barred a Planned Parenthood speaker and an on-campus performance of "The Vagina Monologues," an all-woman play made up of monologues about sex, masturbation and lesbianism.
