Virtually every woman who publicly contributes to a political debate is subjected to virulent and largely anonymous online invective, or "trolling". But it is far more than simply readers' feedback. Trolling is intended to make women shut up - and to remind them their primary purpose is to be there for male sexual pleasure. Or not to be in public life at all.
Twitter, at its best, is a great way to massage your ego (ooh, 15 more followers!), or given my day job, chat with readers (they loved X feature on the site, they thought Y was dull, or words to that effect) and, as I wrote last week, to get breaking news out quickly. At its worst, as Conservative MP Louise Mensch highlighted this week, it's a hot-bed of misogynistic idiots using it to abuse, scare and lambast women in the public eye in the crudest manner possible.
