they are terms which purposely try to define their philosophies in the best possible light, while by definition attempting to describe their opposition in the worst possible light. "Pro-choice" implies that the alternative viewpoint is "anti-choice", while "pro-life" implies the alternative viewpoint is "pro-death" or "anti-life". In part due to this viewpoint, the Associated Press encourages journalists to use the terms "abortion rights" and "anti-abortion". In a 2009 Gallup Poll, a majority of U.S. adults (51%) called themselves "pro-life" on the issue of abortion—for the first time since Gallup began asking the question in 1995—while 42% identified themselves as "pro-choice", although pro-choice groups noted that acceptance of the "pro-life" label did not in all cases indicate opposition to legalized abortion, and that another recent poll had indicated that an equal number were pro-choice. A March 2011 Rasmussen Reports poll concluded that Americans are "closely divided between those who call themselves pro-life" and those who consider themselves as "pro-choice". In a February 2011 Rasmussen Reports poll of "Likely U.S. Voters", fifty percent view themselves as "pro-choice" and forty percent "say they are pro-life". In a July 2013 Rasmussen Reports poll of "Likely U.S. Voters", 46 percent view themselves as "pro-choice" and 43 percent "say they are pro-life".

Similar events take place on a smaller scale in other U.S. cities, such as the Walk for Life in San Francisco, California. The life chain: The "Life Chain" is a public demonstration technique that involves standing in a row on sidewalks holding signs bearing anti-abortion messages. Messages include "Abortion Kills Children", "Abortion stops a beating heart" or "Abortion Hurts Women". Participants, as an official policy, do not yell or chant slogans and do not block pedestrians or roadways. Many Right to Life chapters hold Life Chain events yearly and the annual worldwide 40 Days for Life campaigns also use this technique. The rescue: A "rescue operation" involves anti-abortion activists blocking the entrances to an abortion clinic in order to prevent anyone from entering. The stated goal of this practice is to force the clinic to
