After a spate of suicides among LGBT US teenagers, people across the world will wear purple tomorrow to honour their memory.

More than 1.3 million people have pledged on Facebook to mark ‘Spirit Day’, which was created by Canadian teenager Brittany McMillan.

Ms McMillan wrote on the Facebook page: “It’s been decided. On October 20th, 2010, we will wear purple in memory of the recent gay suicides.

“Many of them suffered from homophobic abuse in their schools or in their homes. We want to take a stand to say that we will not tolerate this.

“Purple represents spirit on the LGBTQ flag and that’s exactly what we’d like all of you to have with you: spirit. Please know that times will get better and that you will meet people who will love you and respect you for who you are, no matter your sexuality.

“Please wear purple on October 20th to remember all the lives of LGBTQ youth that have been lost due to homophobia. Tell your friends, family, co-workers, neighbours and schools.”

Her initiative has also been championed by the Gay and Lesbian Alliance Against Defamation, which urged people to Tweet about the day and turn their Facebook profiles purple.

GLAAD president Jarrett Barrios said: “I will be wearing purple on Spirit Day. The tragic suicides of our youth have started an important dialogue among Americans about the dangers of bullying, and now is the time to show our children that millions of Americans accept and value them regardless of their sexual orientation or gender identity.”

The day follows a YouTube campaign aimed at bullied gay teenagers, which encourages them to stay positive about the future.

It Gets Better was created by journalist Dan Savage and now has a host of celebrity supporters, as well as thousands of home videos uploaded by members of the public.

There have now been at least ten reported suicides of young men and women who were LGBT or were thought to be LGBT in the last month. Most were said to have suffered homophobic bullying.
