Target has issued an apology for offering greeting cards with the phrase "baby daddy" ahead of Father's Day. The retailer pulled those cards from stores.The cards show an African-American man and woman kissing under the words "Baby Daddy."66% of black families are single-parent families, according to the U.S. Census Bureau. Still, this card was deemed inappropriate for singling out African-Americans, who are not featured elsewhere in the card aisle.
