This day was launched in 2004 to draw the attention of policy makers, opinion leaders, social movements, public opinion, the media, etc… to this issue, and to promote a world of tolerance, respect and freedom regardless of people’s sexual orientation or gender identity.
As much as it is a day against violence and oppression, it is a day for freedom, diversity and acceptance as indicated on its official Facebook page.
It remains too much countries which criminalize homosexuality sentencing LGBT people to prison, even to the death penalty. Laws are also very unfavorable to transgenders people in the world.
On May 17th, 1990, homosexuality was take out from the list of mental disorders by the World Health Organization. Since the things changed, as we can see every day through the news, but it still remains much to do. It's necessary to stay mobilized for equality and respect which we all deserve.
