ABOARD THE PAPAL PLANE (AP) — Pope Francis is firmly upholding church teaching banning contraception, but said Monday that Catholics don’t have to breed “like rabbits” and should instead practice “responsible parenting.”

Speaking to reporters en route home from the Philippines, Francis said there are plenty of church-approved ways to regulate births. But he said most importantly, no outside institution should impose its views on regulating family size, blasting what he called the “ideological colonization” of the developing world.

African bishops, in particular, have long complained about how progressive, Western ideas about birth control and gay rights are increasingly being imposed on the developing world by groups, institutions or individual nations, often as a condition for development aid.
