In a conversation with HuffPost Live, the host of the forthcoming TLC series "All About Sex" said Instagram has a responsibility to protect users from pornographic photos.
"Instagram has those rules to protect from pornography and things like that, and kids are on it," McDonald said. "When they [Instagram] take down someone's nipple photo, it's not because they hate women."
McDonald was a frequent guest on "Chelsea Lately", E!'s late-night show starring Chelsea Handler, who famously slammed Instagram for removing a topless photo she posted of herself riding a horse.
