The MFL is a time for pro-life activists to gather and express their opposition to the killing of children by abortion and to promote a defense of life from the moment of conception until natural death.

It is estimated that since Roe v. Wade, more than 58 million American children have been slaughtered by abortion.

Planned Parenthood, the biggest abortion enterprise in the United States, kills more than 300,000 babies every year and receives more than $500 million each year in taxpayer funds.
