Transgender reveal in kindergarten class leaves parents feeling "betrayed"

"Unlike sex education, the topics of gender identity don't require prior parental notice." - Are you kidding me?

Let's take a look at some of the things that occurred and what some of the teachers had to say.
"Parents say besides the books, the transgender student at some point during class also changed clothes and was revealed as her true gender."
""The kindergartners came home very confused, about whether or not you can pick your gender, whether or not they really were a boy or a girl," said England."
""My daughter came home crying and shaking so afraid she could turn into a boy," another parent said."
"Many teachers also spoke out in support of what transpired inside the classroom. They spoke about the importance of teaching students about diversity and having healthy dialogues."
"In a statement during the board meeting, the district said: "As indicated by Superintendent Robin Stout in a communication last week, staff will be engaging parents and teachers in discussions about how materials outside our curriculum will be addressed in the future.""

""When we head in the direction of banned books or book lists, or selective literature – that should only be read inside or outside the classroom, I think that's a very dangerous direction to go," said 7th grade teacher Kelly Bryson." - Curious, what is this teacher's stance on the writings of Mark Twain or Harriet Beecher Stowe.

It seems to me that our educators need some Continuing Education classes on this subject and what their teaching responsibilities are.
