Of course it doesn't say gay. Here's what it actually says:
prohibiting classroom discussion about sexual orientation or gender identity in certain grade levels or in a specified manner
In other words, they cannot discuss about being straight, gay, hetrosexual, homosexual, transgender and such. And we all know what they really are saying. No discussion about being gay or transgender at all.
Also, the bill has a provision for parents to sue if a third party (i.e. other parents) explains it.
Classroom instruction by school personnel or third parties on sexual orientation or gender identity may not occur in kindergarten through grade 3 or in a manner that is not age-appropriate or developmentally appropriate for students
Like I said it will not work. It's going to blow up in their faces.
