(CNN) -- Responding to simmering controversy among Catholic bloggers about her new birth control program, Melinda Gates -- a practicing Catholic -- said she will not shrink from her role as an advocate for poor women. "Part of what I do with the (Gates) Foundation comes from that incredible social justice I had growing up and belief that all lives, all lives are of equal value," said Gates during a recent interview with CNN chief medical correspondent Dr. Sanjay Gupta. About the flak over her Catholicism she said: "We're not going to agree about everything, but that's OK." Gates is promoting an ambitious family planning program -- which includes raising billions of dollars to provide contraceptives to 120 million women worldwide -- at the London Summit on Family Planning July 11.
