SAN FRANCISCO (AP) -- An instructor at a public community college in Fresno has been presenting his religious views on homosexuality, abortion and global warming as fact to students in an introductory health science class, the American Civil Liberties Union alleged Monday.

ACLU staff attorney Elizabeth Gill said at least two students at Fresno City College have complained that instructor Bradley Lopez quoted the Bible as proof that human life begins at conception, characterized homosexuality as a mental illness, and discussed apocalyptic Christian prophesies during a lesson on climate change.

If the students' descriptions are correct, Lopez's teaching methods would violate California laws protecting gays from discrimination and prohibiting religious indoctrination at public schools, Gill said. She sent a letter to college president Cynthia Azaria on Monday asking the school "to act immediately to ensure that all its health classes provide only accurate and unbiased information."

An e-mail to Lopez and a telephone message left at his office were not returned. The college president issued a statement in response to media inquiries.
