An Illinois school district has reportedly banned the otherwise-well-received "The Family Book" because of a reference to same-sex parents.

Think Progress and Joe. My. God. are just two of the media outlets reporting that Todd Parr's children's book has been yanked from a local elementary school's shelves because of a line which notes that "some families have two moms or two dads."

Both sites reference a WHBF-TV Quad Cities report, which quotes Erie School District 1 Superintendent Bradley Cox as saying that several parents argued that the book "discussed different types of family structures" and "those are issues that shouldn’t be taught at the elementary school level."

The original WHBF-TV Quad Cities report appears to have since been taken down.

The winner of two National Parenting Publication Awards and three Oppenheim Gold Awards, Parr has authored over 30 children's books, including "The Feelings Book," "It's Okay To Be Different" and "We Belong Together: A Book About Adoption And Families."
