If one group of people say a woman has a right to choose, I get queasy because I'm against abortion. I don't think a woman has a frivolous right to choose. What I don't want is a desperate woman to die in an illegal abortion.

A woman has a right to a safe, legal abortion. I've never wavered in that position since I was, like, eight years old and realized what was going on when I heard my mother arguing with people about the issue.

The movement across Canada to fight toxic chemicals is a women's movement. It's a concern about health; it's very intimate.
