Last month, a group of parents in Orlando, Florida, demanded “consequences” against sixth grade science teacher Robert Thollander. His crime? Thollander acknowledged his marriage at school.

“He married a man. This alone is not an issue. Sharing the details … with all his 6th grade students is the issue,” the parents wrote in a letter sent to their children’s school board, which was shared with NBC News. “It was not appropriate. Many of these students felt very uncomfortable with the conversations and shared this with their families.”

Had Thollander just “said he will be out for a few days because he was getting married, no problem,” the letter continued, “but to discuss the details and create an uncomfortable situation for the students with no benefit to teaching his subject matter is inappropriate.”

Thollander denied having discussed his marriage since he and his husband tied the knot in March of last year, aside from acknowledging it when he was asked. No action was taken against him by school leaders, who defended him several days later with a letter of their own, he said. Nevertheless, the incident prompted Thollander to make this school year his last after 11 years of working in Florida as a teacher.
