The Sun is under fire after publishing the story of a six-year-old trans boy.
The paper's front page carried the headline "I'm a boy, says twin girl, 6″ - complete with a photo of the child and his identical twin sister.
The paper's splash has been branded "irresponsible and potentially harmful" by LGBT groups.
Many also took to Twitter reacting angrily to the paper's reporting of the child.
Shocking, nasty behaviour from The Sun putting a trans* child on its front page and putting them at risk-- Tara (@Tbirdflieshigh) December 3, 2013
I actually read the front page of The Sun today. The whole thing is flat out hate speech against trans people. I hope the paper fails. Still-- Obtuse™ (@ObtuseMusings) December 3, 2013
Ugh. I just remembered that the Sun have decided to out a trans six year old on their front page, while misgendering him. DIE DIE DIE-- Another Angry Woman (@stavvers) December 3, 2013
Don't even get me started on The Sun's front page today.-- Brad (@spanishturnip) December 3, 2013
In fact I have just seen the front page of The Sun. Deplorable 'journalism' that will likely end in tears at the very least.-- Obtuse™ (@ObtuseMusings) December 3, 2013
The Sun's front page for 3rd December is horrendous. Why?! Why, why, why? Totally gratuitous and can only cause hurt.-- Victoria Cantons (@VictoriaCantons) December 3, 2013
The charity Trans Media Watch (TMW) told Pink News the issue of trans children should be discussed in the media without reference to individual cases.
TMW told PinkNews.co.uk that it was deeply concerned by The Sun's article, arguing it should not have been published, particularly as it identifies the child's school.
"Not only do some trans children not grow up to be trans adults but many may wish to live lives in their real gender where they are not known by people around them to be trans.
"An article like this being available in perpetuity online therefore represents a breach of the child's human rights," the group said in a statement.
The Huffington Post has asked The Sun to comment on this story.
