Parent Sirell Fiel, who read from the handout on Facebook Live, said his seventh-grade son brought both packets home. The students in both grades got all the information, he said, and much of it he considered inappropriate, especially for the younger students.

“I have no problem with the school talking about diversity. Gay kids are out there, and the kids need to know about it. But the problem I have is that it went so in-depth. That’s too much for 11- and 12-year-olds,” Fiel said, noting he had called the school and heard back from the principal, who told him the issue was being investigated.

Martha Harvey, president and CEO of the Pride Center of the Capital Region, said she doesn’t know of any previous time schools or parents have objected to the presentation in the 12 years it has been used in schools.

Harvey would not identify the presenter who went to Cambridge school.

“Transgender kids are coming out younger and younger. Middle school is not too early to start,” said Harvey, who noted that her group was invited to present at Cambridge. “If you love your kids, you want them to have the most information possible. If a parent has a problem with this presentation, that’s the parent’s problem.

“This program saves lives,” she added.
