Frank Zimmerman is a 60-year-old agoraphobic from Gloucester, and last year he wrote to a female MP threatening to kill her children. Like far too many women in public life, Louise Mensch, MP for Corby, often finds herself the target of hate mail and death threats, but she chose to take this one to the police, who quickly traced the violent, sexually aggressive messages to Zimmerman's computer.
Whether or not this recluse intended to carry out his disgusting threats makes no material difference to how Mensch must have felt when she opened that email. This week, Zimmerman was given a 26-week suspended sentence in one of the most high-profile such cases in recent years.
It's always annoying when someone you disagree with on nearly every count is selflessly brave. When I met the Tory MP a few months ago, we argued about abortion rights and whether she can still call herself a feminist while supporting Tory cuts which will have a disproportionate impact on women (clue: not in my book).
Mensch and I don't have a lot in common besides the fact that we both have vaginas and opinions, but those, as luck would have it, are precisely the qualifications that misogynist internet trolls of all political stripes and none are looking for. Abuse of women online cuts across political camps, and chatroom masturbators of all affiliations routinely confuse freedom of speech with freedom to abuse, bully and harass with impunity.
In tackling the troll head-on, Mensch has done a service not only to every woman writing and speaking in public today, but to the next generation of female opinion-makers. It only takes one person to make a stand. In cases of bullying and intimidation like this, precedent is everything, and precedent is something that, in the internet age, we often don't have very much of to refer to.
Ten years ago, politicians, journalists and celebrities might have anticipated the occasional angry letter from a reader, sometimes even a scary letter. Now anyone with a public platform can expect harassment in comment threads, via email and on Twitter, especially if they're a woman or a member of an ethnic minority. I've had to handle threats to my family, too, alongside a daily splatter of missives that range from nastily suggestive to straightforwardly frightening.
Some people might even wonder how this sort of abuse ever became a routine part of public conversation, something that anyone with a public platform is expected simply to "brush off". But as far as I'm concerned, it's all character-building – as long as one wishes to build the character of a paranoid human wreck.
Cases like this need to be brought, and not just because I refuse to carry on living in a society where misogynist keyboard-droolers try to chase any woman with a public profile off the internet. A culture where the only people able to contribute to the national conversation are thick-skinned, insensitive, white, straight males who can repel or ignore this ugly trench of abuse is not a culture any thinking person should want to live in. It's time to take the haters to task.
