I just wanted to take a moment out to add to Medea's post, especially since today also marks a national day of rememberance on violence against women.
Violence against women happens under various conditions but what we know of it and how we know of it gets mediated by the fact that we live in a racist, sexist, homophobic, transphobic, able-ist society--so only certian kinds of violence against certain women gets acknowledged, and paints a particular, limited picture of the issues, when the reality is that there are an abundant. So many histories and conceptions of what we think is a 'liberal'* (read: our) society drastically change when we bother to look under the rug.
So while we remember importantly the Montreal Massacre, let's also remember to read Andrea Smith,Sherene Razack,Angela Davis,Melissa Wright. Let's remember to watch Finding Dawn and The Sterilization of Leilani Muir. Drop by The Centre for Women and Trans People (University of Toronto) and have an important conversation.
There's so much more out there.
Note how many of those few sources I listed point to a Canadian history--including the Massacre. Let's look under our own rug.
*a big problem is understanding just what exactly we mean and politically support when we say 'liberal' in the first place...
