Laurie Penny: A woman's opinion is the mini-skirt of the internet

You come to expect it, as a woman writer, particularly if you're political. You come to expect the vitriol, the insults, the death threats. After a while, the emails and tweets and comments containing graphic fantasies of how and where and with what kitchen implements certain pseudonymous people would like to rape you cease to be shocking, and become merely a daily or weekly annoyance, something to phone your girlfriends about, seeking safety in hollow laughter.

An opinion, it seems, is the short skirt of the internet. Having one and flaunting it is somehow asking an amorphous mass of almost-entirely male keyboard-bashers to tell you how they'd like to rape, kill and urinate on you. This week, after a particularly ugly slew of threats, I decided to make just a few of those messages public on Twitter, and the response I received was overwhelming. Many could not believe the hate I received, and many more began to share their own stories of harassment, intimidation and abuse.

Perhaps it should be comforting when calling a woman fat and ugly is the best response to her arguments, but it's a chill comfort, especially when one realises, as I have come to realise over the past year, just how much time and effort some vicious people are prepared to expend trying to punish and silence a woman who dares to be ambitious, outspoken, or merely present in a public space.

No journalist worth reading expects zero criticism, and the internet has made it easier for readers to critique and engage. This is to be welcomed, and I have long felt that many more established columnists' complaints about the comments they receive spring, in part, from resentment at having their readers suddenly talk back. In my experience, however, the charges of stupidity, hypocrisy, Stalinism and poor personal hygiene which are a sure sign that any left-wing columnist is at least upsetting the right people, come spiced with a large and debilitating helping of violent misogyny, and not only from the far-right.

Many commentators, wondering aloud where all the strong female voices are, close their eyes to how normal this sort of threat has become. Most mornings, when I go to check my email, Twitter and Facebook accounts, I have to sift through threats of violence, public speculations about my sexual preference and the odour and capacity of my genitals, and attempts to write off challenging ideas with the declaration that, since I and my friends are so very unattractive, anything we have to say must be irrelevant.

The implication that a woman must be sexually appealing to be taken seriously as a thinker did not start with the internet: it's a charge that has been used to shame and dismiss women's ideas since long before Mary Wollestonecraft was called "a hyena in petticoats". The internet, however, makes it easier for boys in lonely bedrooms to become bullies. It's not only journalists, bloggers and activists who are targeted. Businesswomen, women who play games online and schoolgirls who post video-diaries on YouTube have all been subject to campaigns of intimidation designed to drive them off the internet, by people who seem to believe that the only use a woman should make of modern technology is to show her breasts to the world for a fee.

Like many others, I have also received more direct threats, like the men who hunted down and threatened to publish old photographs of me which are relevant to my work only if one believes that any budding feminist journalist should remain entirely sober, fully clothed and completely vertical for the entirety of her first year of university. Efforts, too, were made to track down and harass my family, including my two school-age sisters. After one particular round of rape threats, including the suggestion that, for criticising neoliberal economic policymaking, I should be made to fellate a row of bankers at knifepoint, I was informed that people were searching for my home address. I could go on.

I'd like to say that none of this bothered me – to be one of those women who are strong enough to brush off the abuse, which is always the advice given by people who don't believe bullies and bigots can be fought. Sometimes I feel that speaking about the strength it takes just to turn on the computer, or how I've been afraid to leave my house, is an admission of weakness. Fear that it's somehow your fault for not being strong enough is, of course, what allows abusers to continue to abuse.

I believe the time for silence is over. If we want to build a truly fair and vibrant community of political debate and social exchange, online and offline, it's not enough to ignore harassment of women, LGBT people or people of colour who dare to have opinions. Free speech means being free to use technology and participate in public life without fear of abuse – and if the only people who can do so are white, straight men, the internet is not as free as we'd like to believe.
