Yale Law School is fighting internet censorship in schools.

In conjunction with the American Civil Liberties Union, the Law School has started a campaign called “Don’t Filter Me,” which asks students to check and report schools that block LGBT content on the web.

Some schools have blocked access to websites that deal with LGBT rights, such as the GSA Network, or news items like Don’t Ask Don’t Tell. The Law School and the ACLU allege that blocking these websites may violate the First Amendment and the federal Equal Access Act.

“Students may not realize that it actually is illegal for their schools to block educational and political content geared toward the LGBT community,” ACLU attorney Joshua Block told Pink Paper. “We hope to inform students of their rights, and let them know there is something they can do if their school is engaging in censorship.”
