Elliot Page, who currently stars on Netflix's "The Umbrella Academy," came out as transgender on Tuesday.
"I feel overwhelming gratitude for the incredible people who have supported me along this journey," Page, who was previously known as Ellen Page, wrote.
"I can't begin to express how remarkable it feels to finally love who I am enough to pursue my authentic self. I've been endlessly inspired by so many in the trans community."
Page went on to write that although he feels "profoundly happy" about sharing his story, he's also scared "of the invasiveness, the hate, the 'jokes' and of the violence."
"To be clear, I am not trying to dampen a moment that is joyous and one that I celebrate, but I want to address the full picture. The statistics are staggering. The discrimination towards trans people is rife, insidious and cruel, resulting in horrific consequences," he wrote in the letter.
"In 2020, alone it has been reported that at least 40 transgender people have been murdered, the majority of which were Black and Latinx trans women."
The LGBTQ advocacy group Human Rights Campaign reported in October that it recorded more violent deaths of transgender or gender non-conforming people than any year since it began tracking such crimes in 2013.
Page ended the letter by saying that he loves that he is trans and queer.
"And the more I hold myself close and fully embrace who I am, the more I dream, the more my heart grows and the more I thrive," he said.
The post, which has been shared more than 20,000 times, sparked messages of praise.
"So proud of our superhero! WE LOVE YOU ELLIOT! Can't wait to see you return in season 3!" Netflix wrote.
