Two lesbian students in Pompano Beach, Florida, were told repeatedly by the principal that they weren't allowed to hold hands on campus, something that they kept on doing because they saw that straight students were allowed to hold hands.
At one point, the principal rode up on his golf cart, told the girls to "stop do[ing] that," and took them to the office. He called their parents, outing one of the girls to her mother in the process.
The students wrote to the superintendent saying that they shouldn't be held to a different standard, and here's the response they got:
"It is my understanding that the holding of hands on campus is not an acceptable practice at Blanche Ely High School. This practice is applicable to all students, regardless of age, race, disability, sexual orientation, gender identity, gender expression, marital status, national origin, religious sects, as identified in School Board's Nondiscrimination Policy."
What's makes this story interesting is that the girls did not go through an org to get word out, but took it upon themselves to make sure people know what's going on here and to complain to the school board. A local paper covered the story (linked above) and local TV has as well (can't be embedded, img from that video).
