Margaret Downey was born into a multi-cultural family in Baton Rouge, Louisiana. Growing up in a highly prejudiced southern society in the 1950s, Margaret became concerned about persecution from an early age.

She became an openly declared atheist and activist in her twenties. Free from the constraints of religious dogma and patriarchal systems, Margaret became involved with the feminist movement. Margaret fought for basic rights such as freedom of expression, freedom of choice, personal family leave for working parents, equal pay, and promotional opportunities for women.

Being an activist for controversial issues nearly cost Margaret her job thirty-five years ago. The initiatives Margaret worked and sacrificed for then are commonplace today. Even as a single mother Margaret was willing to jeopardize her income to demand respect for women, freedom of choice, freedom of expression, and freedom from religious intrusion.
