Manipulation implies a conscious choice from speakers to trigger a change of opinion in the interlocutors and to make them accept their own point of view, i.e. their own vision of the world. As pointed out by Goatly [2007], Charteris-Black [2005, 2014] or Van Dijk [1998], metaphors can be used as manipulative tools. Metaphors have traditionally been considered as figures of speech used by rhetoricians to convince crowds; cognitivists have demonstrated that they are figures of thought as well, which partly accounts for their manipulative potential. The three underlying reasons to this are, among others, the highlighting-hiding process, the existence of asymmetrical metaphors, and the multivalency of metaphors. The manipulative potential of metaphors is examined in twelve speeches from pro-life supporters, ranging from 2006 to 2019. One of the main ideological debates going on in the US has been on abortion, as the pro-life movement has grown stronger in recent years and has been threatening the right to abortion guaranteed by Roe v. Wade. The study of the metaphors in those speeches has enabled us to highlight how pro-lifers manipulate people regarding the apprehension of reality by systematically using a limited number of conceptualizations.
