"I'm pro-life but I'm not part of the pro-life movement"?

Can anyone from Canada, or conversant with matters Canadian explain this to me?

The Unborn Victims of Crime bill, submitted to the Canadian parliament by Conservative Ken Epp, received its first hour of debate in the House of Commons on December 13.
The bill-- which would allow criminal charges to be laid in the death or injury of an unborn child when the child's mother is the victim of a crime-- faced heated opposition, however. Among the leading opponents was Raymond Gravel, a Catholic priest who was given permission to enter politics by Bishop Gilles Lussier of Joliette.?
"I'm a Catholic priest," said Gravel as he began his remarks on the proposed legislation.?Gravel said he was "uncomfortable" with the bill "because the member putting it forward is part of a group called the pro-life group which in my view is a rather extreme fanatical group, when it comes to life." Gravel continued, "I'm pro-life but I'm not part of the pro-life movement in Canada."??
The priest-- who had promised his Bishop before entering politics that he would not take positions that went against the doctrines of the Church-- added, "I also think this bill will open the door to a re-criminalization of women who have abortions, and that's not to be desired."
