Because they tell us a lot about her critics. A great column by the Toronto Sun‘s Lorrie Goldstein which begins:

The ferocity of the attack on Status of Women Minister Rona Ambrose for voting in favour of a Conservative MP’s motion to study the question of when human life legally begins is not only absurd, it says a lot about the attackers.

Although Goldstein favours maintaining Canada’s abortion license he skewers the pro-abortion lobby that finds Ambrose’s position of exploring the moral implications of what we know about preborn life as a betrayal of women:

What they’re really saying is Ambrose is guilty of thought crime.

That as the minister for the status of women, she has no right to even think about the moral implications of when life begins, other than to think about it as they do, which is to try not to think about it at all.
