Science fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative.

Women in the anti-choice movement want to share in male power over women, and do so by denying their own womanhood, their own rights and responsibilities.
