Because School Administrators, Teachers, and Staff should not allow or engage in bullying of any students GLBT, African American, Latino, Female, Oriental or whatever. Furthermore an Administrator should not tell a student "I don't want a ... in my school" no matter what.
Bullying is not acceptable under any situation. Schools that encourage such activities should have their ability to teach taken from them. This was not a case in which a school administrator told a student that they couldn't do anything because it didn't happen on school grounds or because they just have your word against the bully's. This is a case of school officials allowing and engaging in bullying. And further more a school administrator allegedly saying "I don't want a dyke in my school" when asked to do something about it.
