BOSTON The dozens of people who marched at Boston Common on Jan. 29 to voice their opposition to abortion came prepared to face two different kinds of extreme climates: bitter temperatures and the increasingly pro-abortion political landscape. We had no idea what the turnout would be, Mary Moser, a member of Boston Pro-Life Future who helped lead the event, said after the march was held on a day with below-zero wind chills. We re so happy to see people (of) all ages here and standing up for life for Boston. We re just doing our best to fight abortion extremism, especially in a climate like ours, and with the new administration that we have. It s encouraging to see everyone come out, especially on a frigid day like this, she said.
