April 19th marked GLSEN's 18th Annual Day of Silence. Students in thousands of middle and high schools across the country and around the world took a vow of silence to draw attention to anti-LGBT (lesbian, gay, bisexual and transgender) harassment and discrimination in schools.Here are some facts behind why so many organize and participate in the event:&#8226; Four out of five LGBT students reported being harassed at school in the past year. &#8226; Six out of ten LGBT students said they felt unsafe at school. &#8226; Nearly one in three LGBT students miss school every month because they feel unsafe or uncomfortable.You can learn more by reading GLSEN's 2011 National School Climate Survey.Students typically participate in the Day of Silence by taking a vow of silence throughout the school day, unless asked to participate in class. The event is designed to illustrate the silencing effect of anti-LGBT harassment and discrimination.This year, we wanted to put a face to the voiceless. We asked Day of Silence participants to take part in our "Selfies for Silence" photo campaign. Individuals were encouraged to snap a photo with a printable Day of Silence sign asking them to share what they are doing to end the silence around anti-LGBT harassment and discrimination.As a result, GLSEN has been collecting and sharing hundreds of selfies from students and adults across the country.There are a few who grossly mischaracterize the Day of Silence. On April 4 and 10, Mission: America's Linda Harvey made a series of false, sensationalized claims about the student-led event. GLSEN produced a video to correct the inaccuracies and underscore the significance of the day.The video attracted considerable attention online with more than 32,000 views and coverage found onUpworthy,BuzzFeed and The Huffington Post.The Day of Silence continues to be one the largest student-led actions in the country. And support for the day can also be found outside of schools.Day of Silence resolutions to commemorate the event were introduced in six state legislatures, including California, Illinois, Michigan, New York, Ohio and West Virginia.Plus, Rep. Eliot Engel (D-NY) introduced a resolution in the U.S. House of Representatives. And others like Rep. Sam Farr (D-CA) vocalized their support for the Day of Silence.Andy MarraAndy Marra is the Public Relations Manager for the Gay, Lesbian &amp; Straight Education Network (GLSEN).
