Pursuant to my post pointing to Craig's links on the Montreal massacre, Jill at Feministe provides a perspective on it as a US feminist:
Feministe - In Remembrance: The Montreal Massacre: Sixteen years ago, this tragedy mobilized Canadians to address the issue of violence against women. Gender-based violence is certainly not a problem that we’ve solved yet, and it remains a far-reaching one. It’s just usually quieter and more private than this.
This man’s act was intended to terrorize women everywhere, and his aim was to scare them back into traditional roles. He thoroughly failed: From 1989 to to 1999, the number of women in Canadian engineering schools more than doubled, to more than 9,000.
Like I said, this was big news in Canada and is every year, but it's a nonissue in the US. Which is par for the course: it's two different countries. But despite Canadians' occasional smugness (and occasionally deserved smugness), it's a problem that affects both countries, and it has similar solutions.
