Kelly Marie Tran refuses to be marginalised by online trolls.

The 'Star Wars: The Last Jedi' star deleted her Instagram account earlier this year after being subjected to racist trolls and now, speaking out for the first time about her decision, she has shared how she ''started to believe'' their nasty words.

She explained: ''It wasn't their words, it's that I started to believe them. Their words seemed to confirm what growing up as a woman and a person of colour already taught me: that I belonged in margins and spaces, valid only as a minor character in their lives and stories. And those words awakened something deep inside me - a feeling I thought I had grown out of. The same feeling I had when at 9, I stopped speaking Vietnamese altogether because I was tired of hearing other kids mock me. Or at 17, when at dinner with my white boyfriend and his family, I ordered a meal in perfect English, to the surprise of the waitress, who exclaimed, 'Wow, it's so cute that you have an exchange student!'

''Their words reinforced a narrative I had heard my whole life: that I was 'other,' that I didn't belong, that I wasn't good enough, simply because I wasn't like them. And that feeling, I realise now, was, and is, shame, a shame for the things that made me different, a shame for the culture from which I came from. And to me, the most disappointing thing was that I felt it at all.''

Following her distressing experience, Kelly has decided to fight for a better world, where all races, genders and religions are accepted.

In an op-ed for the New York Times, she added: ''I want to live in a world where children of color don't spend their entire adolescence wishing to be white. I want to live in a world where women are not subjected to scrutiny for their appearance, or their actions, or their general existence. I want to live in a world where people of all races, religions, socioeconomic classes, sexual orientations, gender identities and abilities are seen as what they have always been: human beings.

''This is the world I want to live in. And this is the world that I will continue to work toward. These are the thoughts that run through my head every time I pick up a script or a screenplay or a book. I know the opportunity given to me is rare. I know that I now belong to a small group of privileged people who get to tell stories for a living, stories that are heard and seen and digested by a world that for so long has tasted only one thing. I know how important that is. And I am not giving up.''
