An irate father is demanding that Bozeman High School present students with a rebuttal to what he called "extremely biased religious dogma" delivered by an assembly speaker who warned teens against the dangers of drugs, drinking and premarital sex.

Tom Wells, a Bozeman attorney and father of a ninth-grader, told the School Board on Monday night that he was appalled by the "thinly veiled ministry" and "misinformation" presented the week before by speaker Tina Marie Holewinski.

Holewinski, 27, of Hollywood, Calif., a full-time speaker with an organization called True Lies, defended her talk Tuesday as full of "hard-core facts" that could save teenagers' lives.

She denied that she interjected any of her religious beliefs in the talk, and added she'd been flooded with e-mail messages from grateful teens.

Principal Godfrey Saunders said Holewinski had presented the messages school officials are most concerned about each spring, with prom and graduation approaching - Don't drink, drink and drive, don't use drugs.

But, Saunders said, she had gone beyond what they were expecting to present her own views about abstinence.

Saunders said he had spoken to students through the school intercom the next morning to say that what Holewinski discussed about condoms and birth control pills isn't what is taught in the school's sex-ed curriculum, though it also emphasizes abstinence.

"She went off-message," Superintendent Mike Redburn said. "We share (Wells') concerns."

Wells demanded the school give equal time to rebut the "misinformation" his son heard: that condoms lead to cancer, that birth control pills are only 20 percent effective, that sexually transmitted diseases are spread by skin contact alone, that third-trimester fetuses can be aborted, that video games lead to homicide, that human papilloma virus can be transferred through condoms and that teens can achieve "second virginity" through abstinence.

Holewinski responded that she spoke mainly against against drugs, drinking and driving, and debunked "the media's" glamorization of sex, alcohol, drugs and violence.

She maintained it's true that there are cancer-causing agents in latex condoms; that 80 percent of teenage girls who seek abortions are already on birth-control pills; and that human papilloma virus is small enough to pass through condoms. She said she does promote the idea of second virginity.

The school paid Holewinski paid $1,500 for her talk and expenses.

Pat Strauss, assistant principal, said much of Holewinski's talk did cover what they'd asked for, but then all of a sudden she'd throw in zingers, like condoms have 15 different carcinogens, or that birth control pills cause cervical cancer or sterility.

The reaction from the 1,800 students was split 50/50, he said. Some teachers said the talk prompted some lively discussions.

"We tried to do something good for our kids - be safe, get everybody through graduation," Strauss said. "That's what's most disappointing."

A cursory review of Internet sites on just one of Holewinski's disputed topics turned up numerous sites asserting condoms are linked to cancer; however, the pro-condom Planned Parenthood site contends that abstinence-only supporters have put out a number of myths about condoms over the years.

The U.S. Food and Drug Administration Web site doesn't discuss any condom-cancer link. It does say, "a condom could save your life" by greatly reducing the chances of getting sexually transmitted diseases, especially AIDS. It adds, "sex with condoms isn't totally 'safe sex,' but it is 'less risky' sex."
