If you've got a lesbian, gay, bisexual, and transgender (LGBT) club at your high school, can you access the sites of major LGBT civil rights and advocacy groups? If not, the American Civil Liberties Union wants you to report the blocking to its Don't Filter Me campaign.

"Gay-straight alliances and LGBT support groups must have the same access to national organizational websites as other groups such as the Key Club and the chess club," the ACLU's advisory page on the problem explains. The civil liberties outfit says it was alerted to the blocking problem when a student sent the group a screenshot of his attempt to access the Gay, Lesbian, and Straight Education Network site.

"You have been denied access as it is characterized as LBGT," the page warned. "Your Internet usage is monitored and logged."

The ACLU charges that such blocking violates both the First Amendment and the Equal Access Act, a law that forbids "content-based discrimination against student speech," by the Department of Justice's interpretation. The legislation was originally lobbied for by religious organizations that wanted to run Bible study groups in public schools.

Almost two years ago, the ACLU ran a pressure campaign against two Tennessee public school districts that used Web filtering software to bar student access to the sites of nationally known LGBT groups. While the software blocked these sites, it did allow access to various "reparative therapy" and "ex-gay" programs.

Eventually, the company that provided the software to over 100 Tennessee schools fixed the filters to allow access to pro-LGBT Web portals (at about the same time, consumer dismay convinced Microsoft to stop blocking LGBT identification terms on Xbox Live).

Now the ACLU wants students to go to its filter checklist and, while sitting at a campus computer, see whether any prominent LGBT sites are filtered out.

"If your school doesn't block ANY of these websites, that's wonderful! There's no need for you to contact us, so you don't have to submit this form," the page says.

But "if any of the websites were blocked, we'll get in touch with you. If your school is illegally censoring your access to information, we may be able to help you fight back!"
