Atheists and secularists generally pride themselves on respect for science, opposition to harmful religious myths, and a fierce defense of the separation of church and state. Yet there is a critical need for atheists and secularists of conscience to collectively challenge the current moral, cultural, and political siege upon women’s right to self-determination. Flowing from each of these principles, we call on atheists and secularists to make public their support for women's right to abortion and birth control. Due to the insidious climate of anti-abortion propaganda and legislation these basic rights are being viciously imperiled.
