A lecture by Conservative MP Stephen Woodworth came to an abrupt and bizarre end at the University of Waterloo on Wednesday night. Protesters — including one dressed as a large vagina — prevented the staunch, anti-abortion politician from speaking.

The National Post reports the ringleader was Ethan Jackson, a 21-year-old student from nearby Wilfrid Laurier.

“We’re not going back to this,” Jackson shouted. “Who do you think you are trying to impose your bigotry, your views on society through your Christian monotheism?”

Jackson told The Post that his costume — which he calls Vulvetta — was intended to shock the Kitchener Centre MP.

“We decided to go by the route of using satire instead of intimidation,” he said. “We decided to make Stephen Woodworth feel as uncomfortable as he makes us feel.”

Woodworth told the anti-abortion site, LifeSiteNews, that he was disappointed more respect wasn’t shown at the event, organized by campus club, Students for Life.

“The conduct of these protesters suggests they may consider the philosophy of hatred and disrespect for others to be a virtue rather than the self-limiting prison it really is,” he said.

Woodworth believes that babies inside the womb should be recognized as legal human beings in Canada. Currently, the Criminal Code defines a child as human only after it emerges alive from the mother’s body.

The Tory backbencher filed a motion last year to determine when a human being is formed and what the consequences would be if a fetus was recognized as a human being before leaving the womb.

The controversial Motion 312 was seen by many as an attempt to reopen the abortion debate in Canada. It was defeated in September by a vote of 203-91. Prime Minister Stephen Harper voted against it, but 10 of his cabinet ministers – including Status of Women Minister Rona Ambrose – supported Woodworth.
