I've noticed that everyone who is for abortion has already been born.

The line is a pointed, ironic critique of pro-choice advocacy: it suggests that those who support legal abortion do so from the secure position of having survived birth, and therefore cannot fully represent the interests of the unborn. Rhetorically, it reframes the abortion debate as a question of whose rights are being considered and highlights an asymmetry of power and voice between born adults and fetuses. As a piece of political epigram, it aims less to argue policy details than to provoke moral intuition—implying that support for abortion is self-interested or lacks empathy for those who cannot speak for themselves.
