The fury of parents for the "one-sided" transgender drama by Anna Friel, Butterfly, who "encourages children to exchange sex"

Activists have accused the creators of a new ITV drama of creating little more than "advertising" for activists who support children who change sex.

Butterfly, a three-part series that begins tonight, examines the emotional turmoil of alien parents Vicky and Stephen as they try to support Max, their 11-year-old son who identifies herself as a girl.

The writer Tony Marchant of Butterfly & # 39; s Bafta and actress Anna Friel, who plays Vicky, have praised the Sirens, a charity that supports transgender children and their families.

Campers have said that the new ITV Butterfly show that sets Anna Friel (pictured) is an & # 39; announcement. for activists who support children who change sex

On the show the parents Vicky (played by Anna Friel) and Stephen (Emmet J Scanlan) try to support Max (Callum Booth-Ford), their 11-year-old son who identifies herself as a girl

In particular, they paid tribute to the CEO Susie Green, who was a program consultant. Sirens has attracted controversy for calling for an end to the 16-year-old NHS age limit for prescribing sex-change hormones that can lead to infertility.

Transgender Trend, a group that is alarmed by the growing number of sex-changing children, says that Butterfly producers have failed to look for their experience and have created a "one-sided narrative".

Spokesperson Stephanie Davies-Arai told The Mail on Sunday: "It seems that the programmers have advertised trans-activist groups such as Sirens, which would make the world believe that children deny that drugs change sex or self-harm or even they commit suicide, although there are no official figures to support this.

"ITV made no effort to speak to any of the hundreds of parents in my group who believe they are doing the right thing by not validating their child's desire to be the opposite sex.

"If they did, they may have discovered that many of these children suffer from other mental health conditions such as autism.

Group Transgender Trend said only talking about the benefit of Sirene, the show has created a "unilateral narrative". In the picture is the cast (from left to right) Sean McGinley, Alison Steadman, Anna Friel, Callum Booth-Ford, Emmet J Scanlan and Millie Gibson

"They may have discovered that, often in the case of girls, they develop a disregard for their body during puberty – perhaps in response to insane pressures that young women are now under having the perfect body, so the fear these parents have is that their son mistakenly believes that they were born in the wrong body when they actually have a very different problem. "

Lily Maynard, who has a personal experience of the issues raised in Butterfly, saw a preview of the opening episode with "growing discomfort". Ms. Maynard allowed her 15-year-old daughter to dress as she wished, but prevented her from taking cross-sexual hormones at that age.

"I was impressed that the program accepted sexist stereotypes," he said. "No one ever suggests that he does not need to" fix "and that it is the fault of gender stereotypes appreciated by all those around him".

The Mail on Sunday revealed at the beginning of this year that a third of minors referring to the only gender identity service of the NHS of Great Britain for children under 18 have signs of autism. Among the general population, one in 100 is autistic.

A preview of the drama describes how Vicky allows Max, played by Callum Booth-Ford, to dress up with feminine clothes and to support the desire to be a woman, while trying to ensure that the child's mental health is "kept intact" at all costs". But Stephen struggles to face opinions "does not understand" and Max's grandmother represents "generational ignorance" because she believes that Max is going through a "stupid phase".

The Red Production Company, which has made Butterfly, said it had consulted extensively with experts, children and families about their experiences.

Ms. Green said, "Mermaids have never claimed that children who deny cross-sexual hormones can self-harm."
