Feminists often see abortion restrictions as a way to remove female control over their labor, sexual practices, and reproductive decisions. Pro-life advocates often deny such motives, arguing that they only care about stopping the murder of "unborn humans" and the trauma associated with having an abortion. This study addresses these concerns by studying the role of gender attitudes in anti-abortion activism. By using the 2010-2012 Evaluations of Government and Society Study ANES Surveys (n = 3,860) to determine who joins pro-life social movements, this study concludes that pro-life activism is connected to beliefs about stay-at-home mothers, perceptions of sexism in society, being married, and exposure to political conversations in political groups, religious institutions, and families.
