A Tennessee school district has unblocked GLBT issue oriented websites in response to an ACLU federal lawsuit, the Knoxville News Sentinel reported.

The American Civil Liberties Union (ACLU) and the ACLU of Tennessee sued Metropolitan Nashville Public Schools and Knox County Schools in May, charging the schools with unconstitutionally blocking students from accessing online information abut lesbian, gay, bisexual and transgender issues.

While the school's Internet filter blocked GLBT issue oriented websites, student were free to access anti-gay sites.

Filtered sites included prominent gay and lesbian rights organizations including Parents, Families and Friends of Lesbians and Gays (PFLAG), the nation's largest support group for gay allies, the Gay Lesbian Straight Education Network (GLSEN), a group that supports student gay-straight clubs, and the Human Rights Campaign (HRC), the nation's largest gay and lesbian rights advocate.

Not filtered were sites that support so-called reparative therapies, a combination of pseudo-science and ministry aimed at “curing” gay men and lesbians, also known as the “ex-gay” movement.

“Allowing access to Web sites that present one side of an issue while blocking sites that present the other side is illegal viewpoint discrimination,” Catherine Crump, an ACLU staff attorney, said in a statement. “This discriminatory censorship does nothing to make students safe from material that may actually be harmful, but only hurts them by making it impossible to access important educational material.”

Officials at the Knox County Schools called the blocking of GLBT sites a “glitch” and reported on Wednesday that it had been corrected.

“We began working to find a solution to this issue, in good faith, as soon as it was brought to our attention, and our efforts were actively under way long before the legal action recently taken by the American Civil Liberties Union,” Knox County Schools Superintendent Jim McIntyre said in a statement.

All adult-oriented websites remain inaccessible to students.
