A parental backlash to a teacher reading a book that involves a gay couple to students has led to the teacher's resignation.

Omar Currie read King & King, in which two princes fall in love and get married, to his third grade students after he saw one of his students being teased and called gay in a derogatory way, the News & Observer reported.

In response to complaints from parents, Currie's school, Efland-Creeks Elementary in Efland, North Carolina, instituted a new policy requiring teachers to submit a reading list to parents for their approval prior to their introduction in the classroom.

At a packed meeting held in May, parents criticized Currie's actions.

“This is nothing more than bringing homosexuality into a school where it does not belong,” grandmother Lisa Baptist told officials.

Currie, who is openly gay, said that he decided to leave because he felt school administrators did not support him despite a review committee's finding in his favor.

“I was told that it's controversial, which means all LGBTQ families are controversial,” Currie told the News & Observer. “If you're directing me to that policy based on the King & King, then you're directing every single teacher to that policy when they read any book that reflects that population.”

Meg Goodland, the assistant principle who lent Currie the book, also resigned.
