Another thing that Margaret Sanger had to overcome is the Comstock Acts. The Comstock Act was proposed to congress and put in place in 1873 to ban contraceptives with the argument that birth control is obscene. This made distributing anything related to birth control, and birth control itself illegal.

Because of this, women had to take dangerous measures and get incredibly unsafe abortions. Margaret Sanger’s goal was to rid of these laws and make birth control and family planning implemented into normal American society, making sure everyone had equal access to them.
