UNION, Ky. (AP) — A national anti-abortion group says a northern Kentucky high school student's right to free speech is being denied after a principal deemed the content of flyers he created "too controversial" to post around the campus.

The Kentucky Enquirer (http://cin.ci/1ZA2lAw) reports Students for Life of America said in a release that Ryle High School Principal Matthew Turner rejected six of seven flyers created by 18-year-old senior Patrick Edwards, who wanted to post them to advertise the school's Students for Life club.

A letter from attorneys for Students for Life demands that Turner allow the flyers to be posted by Oct. 20 or it threatens to sue.

Turner said the district's attorneys are reviewing the letter, but that "the policies we have in place are in full compliance with the law.

"We don't discriminate against students or student organizations or students with opinions."

One rejected flyer has a picture of a panda holding a sign that says "Save the baby humans." Another has people holding signs that say "I am the pro-life generation."

"Other student clubs and students have been allowed to post fliers taking various positions and I was specifically told my fliers could not be posted because the issue was too controversial," Edwards said in the release. "I believe it's important to be able to share positive pro-life messages with my peers, especially with students who may be facing an unplanned pregnancy or know someone who is. Our aim is never to discriminate but to lovingly present the pro-life message and make a positive impact on our school community."
