The Utah lawmaker who led the charge in an anti-porn crusade is gearing up to introduce a handful of bills during next year's legislative session designed to heavily restrict access to pornography across the state.

Republican Sen. Todd Weiler said his resolution declaring pornography a public health crisis, which sailed through the 2016 session, was only the first step. He plans to introduce at least three new proposals next session including one requiring Internet service providers to add filters so everyone in Utah has to opt-in to view pornography.

The work to rid the predominantly Mormon state of what some consider harmful material echoes an argument made by many conservative religious groups across the country as porn becomes more accessible on smartphones and tablets.

The Mormon lawmaker said he has also looked to England's success with a similar program for guidance.

Prime Minister David Cameron announced in 2013 that Internet service providers would give customers the option of filtering out pornography. Earlier this week, the government revealed plans to add a new law requiring age verification for those websites that include pornographic material.

Pete Ashdown, founder of Salt Lake City-based Internet provider XMission, said completely filtering the Internet of porn is impossible from a technological standpoint, citing China's failure to fully restrict its citizens access to certain parts of the Internet. He said it would likely involve finding and filtering out each individual website that contains porn.

"Trying to control the Internet in these broad stroke ways never works," he said. "Whether you're an autocratic government trying to tell people that democracy is not good for them or an uptight legislator in Utah telling everyone what is pornography and what is not pornography."

First Amendment lawyer Andrew McCullough says such a requirement would restrict free speech, as it would involve blocking certain postings.

"I really don't expect that the state of Utah is going to be able to exercise that kind of control over an interstate item such as the Internet," he said. "I don't think they have the jurisdiction to."

Some key Utah officials, including Gov. Gary Herbert, have spoken out against pornography, calling it such things as a plague, pandemic and scourge that warps children's minds, threatens marriages and contributes to sexual violence.

Dozens of people packed a room at the state Capitol last month for the porn resolution's ceremonial signing. Many were young people wearing T-shirts with the phrase, "Porn kills love."

Weiler said his other two bills would help to restrict kids' access to pornography by adding filters on IPhones and tablets, and in libraries.

The idea would be that these devices would come pre-installed so that they filter out porn sites, he said. In order to remove the filter, the user would have to prove that they're at least 18 years old.

"How ludicrous is it that a 16-year old-kid can't go see Fifty Shades of Grey, but as they're walking back to their car, they can pull an Apple IPhone 6 out of their pocket and they can watch hardcore graphic videos on their phone," Weiler said.

The idea for adding filters in libraries came in part after a mother contacted Weiler about her teenage son who said he can't see porn on his home computer so he goes to the library to access it.

Utah Library Association past president Dustin Fife said in a statement that the bill would be redundant since most public libraries already have some form of a filter.

The National Center on Sexual Exploitation recently released a statement in which it praised Weiler's efforts to protect children from pornography on the Internet at public libraries.

Critics say Utah is overstating the effects of pornography, which some say can be a healthy sexual outlet for adults.

Mike Stabile, a spokesman for the adult entertainment trade group Free Speech Coalition, said adults should have the freedom to learn about sexuality and be entertained by it.

"It always comes down to legislators wanting to control what people see and do in the privacy of their own home," he said
