Fifty Shades Of Grey hits cinemas this week among a flurry of discussions about sexual liberation, erotica becoming mainstream and how good looking Jamie Dornan is.

But a lot of people have suggested Christian Grey’s treatment of his lover Anastasia Steele in the EL James adaptation looks uncomfortably like an abusive relationship, both physically and emotionally.

Natalie Collins started the 50 Shades Is Abuse campaign two and a half years ago when she first read Fifty Shades of Grey. Tonight, she’ll be protesting outside the UK London Film Premiere at the Odeon Leicester Square.

“We’re protesting because we want to have a voice there. The campaign doesn’t aim to censor the film, we just want to create a presence that’s offering a different perspective,” Collins said.

The protesters will start to make their presence felt as soon as the film cast begin to arrive.

She said: “We want to hold accountable the people who are capitalising from it.”

But, she added: “I don’t think that any one person is responsible. EL James is not an expert in domestic violence. She doesn’t understand the issues. It’s gone beyond just being a film or a book. It’s becoming part of popular culture in a really disturbing way.”

Shortly after Collins started the campaign, she was contacted by a number of women who found the novel troubling, and even traumatic, because of the way it reflected their personal experiences of psychological abuse.

“We got lots of women telling us that that’s something that was very difficult for them,” she said.

One of these women was Emma Tofi, who now runs the social media for the campaign. She started reading Fifty Shades of Grey only a matter of months after getting out of an abusive relationship.

“It’s really ironic,” she said, “I started reading it because I wanted to restore my faith in romance…I really wanted to be a fan of it.

“But unfortunately it felt really uncomfortable…I felt like I was reading my life story.”

The phrases and justifications Christian Grey uses in the novels, she said, echoed what her abusive partner had said to her almost word for word.

“Reading Ana falling for the same thing was very hard,” she said. “There were genuinely nights where I’d read a few chapters and then sob myself to sleep. I felt alone and like I was the only person experiencing this.”

Since then Tofi has written extensively on the subject, publishing the comprehensive Fifty Abusive Moments in Fifty Shades of Grey this month. Hundreds of people have engaged with it since, making personal disclosures about their experiences.

Tofi said she’s reached out to James but said: “What upsets me personally is that she’s very dismissive to this sort of criticism.”

Tofi added that when she was with her partner, she didn’t realise she was being abused because her partner was never physically violent. It was only when a counsellor recognised it that she came to understand how she was being manipulated.

“Thousands of women don’t acknowledge emotional and psychological abuse,” she said, “so romanticising signs of it is dangerous.

“Valentine’s Day is commercialised, but it’s a day to celebrate love.  A man gaining access to a woman’s bank account, making threats to her in a non-sexual manner and stalking her is not love.

“The fact that he is also being promoted as a ‘fallen hero’ and sold as a romantic feels like a bit of a slap in the face.”

While hundreds of people have engaged with the subject on Twitter using hashtags including #ItsOnUs#BlueAboutGrey and #50DollarsNot50Shades, Collins said she won’t have a firm sense of how many people will turn up to the premiere to protest until the moment she gets there.

“It’s all going ahead though,” she said determinedly.
