Potential new lesson plan on sex-ed, gender identity raising some concerns among New Jersey parents

There is controversy in at least one New Jersey school district over a potential new lesson plan on sexual education and gender identity. 
A proposed lesson plan distributed to parents in Westfield includes teaching first graders to define sexual abuse and second graders to identify male and female genitalia.
The proposed state standards say by the end of second grade, children should know that "all living things may have the capacity to reproduce" and by fifth grade that “pregnancy can be achieved through a variety of methods."
Jim Boyes, a parent in the district, says he doesn’t believe “this is an issue that mandates any type of governmental action."
“I think that it's actually damaging to the development of children and I think that we should just let kids be kids,” says Boyes.
School districts have a September deadline from the Murphy administration to follow updated health and physical education standards. Gov. Phil Murphy said on “Ask The Governor” Monday that parents “absolutely” deserve a say in the curriculum and can opt out. 
Rep. Jefferson Van Drew announced he will be introducing legislation, the "My Child, My Choice" Act, in response to the state of New Jersey indicating that beginning in the fall, second graders will be taught about gender identity. 
The proposed lesson plans in Westfield were devised by Advocates for Youth, a group that says it "champions programs that recognize young people's rights to honest sexual health information."
