The 29-year-old was forced to address comments seemingly made about him by Bryan Fuller earlier this week.
Heroes star Thomas Dekker – who played Zach on the NBC series – has come out publicly as gay and revealed that he married his husband back in April.
It comes after former Heroes exec Bryan Fuller stated at Outfest that a planned gay storyline was axed by the show following a behind-the-scenes dispute with the actor it involved.
“The gay character was het-washed after the actor’s management threatened to pull him from the show if [the character] were gay,” Fuller claimed.
However, Thomas has now confirmed that it was himself who the claim was about, and used the opportunity to explain his decision.
“My sexual orientation once again came into question this week when a prominent gay man used an awards acceptance speech to ‘out’ me,” Thomas said on Instagram.
“While he did not mention me by name, the explicit details of his reference made it easy for the public and media to connect the dots.
“While it is an odd situation, I thank him because it presents a prime opportunity for me to publicly say that I am indeed a man who proudly loves other men. In fact, this April, I married my husband and I could not be happier.”
Thomas continued: “I have never lied to the press about the fluidity of my sexuality but this man claiming that I came out is not true. Because I have not ‘officially’ until this moment. I simply refuse to be robbed of the glorious joy that belongs to me.
“To say the words myself. ‘I’m gay’. Those words are a badge of honor that no one can steal.
“Sexuality and who you love is a deeply personal and complicated thing. For some of us, it takes time to cultivate, discover and conclude. It is not something anyone should ever be ashamed of and certainly not something anyone should be rushed into.
“I agree with many who believe it is an important responsibility for LGBTQ persons with a platform to come out. It has the power to change minds, challenge beliefs and make others feel understood and supported. It can strengthen the progression of our community and help disarm those who discriminate against us.
“It is a brave, powerful and important thing to do but it is also a deeply personal decision. One that should only be made when you are ready.
“If we are to stand strong in the gay community, our mission should be support, not exclusion; love, not shame. I choose not to look back on the past with a regretful heart but rather focus on the future with a hopeful one. A future where myself and all others can feel free to express their true selves with honor and dignity.
“I embrace you, any of you, with open arms, kindness, faith and patience. For all of you who have supported me, before and now, I thank you from the bottom of my fledgling heart.
“Be proud of who you are. No matter how long it takes.”
Thomas has starred in a number of shows throughout his career so far, including Terminator: The Sarah Connor Chronicles, The Secret Circle and Backstrom.
