On Wednesday, I saw Bitch Boxer at the Soho Theatre; a one-hour, one-woman play written and performed by Charlotte Josephine. Having seen Josephine in Julius Caesar earlier this year, I was excited to see her own work – and, to be honest, I’m a bit in love with the Soho Theatre and their apparent directorial policy of ‘stage work that Sophie wants to see, and don’t charge her more than a tenner for doing so’. For me, Bitch Boxer was an incredibly inspiring, salutary and encouraging piece of theatre. Alongside my fascination with the play’s story and characters, I was delighted to see such a young writer and performer performing with such skill and immediacy – and being so warmly received.

Bitch Boxer is the story of Chloe, a young working-class boxer from Leytonstone, East London, who is gearing up for her final qualifying fight before the London Olympics; the first Olympics in which women could box. I am a bespectacled, myopic, borderline-dyspraxic, undersized and severely uncoordinated scrap of laziness, and I came out of Bitch Boxer wanting to box. The play’s exposition of the sport’s technical side is unexpectedly fascinating. I also found Bitch Boxer a more complex and nuanced exploration of boxing than On It, Tony Pitts’s recent Afternoon Play about the late Liam Jones, a young drug addict who attempted to conquer his addictions via boxing. Both plays tell powerful stories of pain and loss, but Bitch Boxer gets far further beyond the predictable narrative of boxing-as-emotional-salvation. Not only does Chloe use boxing to express and control her adolescent anger, but training and fighting give her an identity that reorders and reorients the rest of her life. Bitch Boxer‘s most emotionally articulate scene is Chloe’s recognition that her opponent in the ring is as determined, excited, frightened and committed as herself. This gives the boxer a compassion and respect for the process of fighting that makes the final confrontation moving, but not mawkish.

I said that Josephine was warmly received by her audience, and the vast majority of the reviews have also been excellent. However, one critic has objected in misogynist – and also misspelt – terms that Charlotte Josephine’s body is not plausibly that of a boxer, and that this physical dissonance damages the integrity and believability of the piece. That is an extremely polite paraphrase of what this lone lunatic actually came out with, and I’m not going to link to the review, because, well, don’t feed the trolls.

Firstly, Charlotte Josephine’s body is very plausibly that of a boxer. Secondly, and not to position myself as the tiny Cassandra of critical misogyny, but after watching Bitch Boxer, I was expecting to find that this kind of play would draw this kind of criticism. Women cannot put their bodies out in public looking like Charlotte Josephine looks, without attractive derisive male comment. Josephine looks fit and strong, in a way that’s toned but which connotes substance, strength and stamina, rather than the ultra-tiny LA yoga bod that’s the  mainstream default and pinnacle of the sporty female body. She looks admirably powerful. It’s not really surprising that a woman daring to be visibly sporty, healthy and herself causes controversy: for God’s sake, look at what happened to Rebecca Adlington and Jessica Ennis.

I sat there watching Josephine and I thought how brave she was not to be in Sweaty Betty pinkified sports gear, but instead to look like a boxer, in Lonsdale shorts, black ankle socks and an ordinary vest; all of them sweat-soaked, as the intensely physical piece progressed. And then I wondered what the hell had happened to society, and to my brain, that I found it brave for a young woman to dress as her character without concessions to sexiness, and that I couldn’t ever remember seeing an actress visibly sweat. In order to bring out the troll in one theatrical critic, all Charlotte Josephine had to do was be visible as a professional and as an artist. Quite often, that is all we have to do, as women, to infuriate misogynists: just show up. I encourage you to show up at Bitch Boxer, as soon as you can.

A Snuff Box Theatre production, Bitch Boxer runs at about 65 minutes, includes Eminem karaoke, bereavement, a confrontation with a savage dog, and a controversial pair of Nikes. With Julius Caesar only last month, I’m suddenly incredibly hopeful about the future of feminist theatre.
