Just days after the tragic suicide of Leelah Alcorn, hundreds of thousands of people have signed a Change.org petition calling for a nationwide ban on therapies that aim to alter the gender identity of transgender teens.

Alcorn, 17, committed suicide in the early hours of Sunday by walking in front of a tractor trailer near her hometown of Kings Mills, Ohio.

A heartbreaking Tumblr post in which she blames her Christian parents for her death quickly went viral.

In her post, scheduled for publication after her death, she said that she knew she was transgender since the age of 4 and that her mother told her she was “wrong.”

“My mom started taking me to a therapist, but would only take me to christian therapists, (who were all very biased) so I never actually got the therapy I needed to cure me of my depression. I only got more Christians telling me that I was selfish and wrong and that I should look to God for help,” Leelah wrote.

Her note ends with an appeal to reduce the number of transgender people who commit suicide.

“I want someone to look at that number and say 'that's fucked up' and fix it. Fix society. Please,” she pleaded.

A Change.org petition calling for a nationwide ban on such therapies has racked up more than 250,000 signatures as of Saturday afternoon.

“In the pursuit of honoring Leelah's last request we the petitioners call upon the President of the United States – Barack Obama, and the Leadership of the House and Senate to immediately seek a pathway for banning the practice known as 'transgender conversion therapy.' We ask that you name the bill in memory of Leelah as the Leelah Alcorn Law and protect the lives of transgender youth,” the petition states.

“'Conversion therapies' have been documented to cause great harms and in this case, Leelah's death. Therapists that engage in the attempt to brainwash or reverse any child's gender identity are seriously unethical and legislation is needed to end such practices immediately. Transgender youth have one of the highest suicide rates in the nation. We must not allow therapists to increase those rates with therapy methodologies that have been demonstrated in harming transgender youth.”

“All major psychological associations speak to the heart of harms that can happen to transgender youth when attempting to discriminate and change their gender identity.”

Hundreds also gathered Friday in Columbus, Ohio and across the U.S. to remember Leelah Alcorn.
