It's not that you only got the bill and the walkout incorrect - it's that you made up what it's about.
There are no programs in those years which teach children about gender-queer.
Here's the reason for the walk out and here is in summary what the bill says.
----------------------
"The bill “Do not say gay” makes it illegal in practice for educators who teach kindergarten through 3rd grade to discuss queerness or queer people with their students at all, even if the concepts of sexual and gender identity are not actually taught at that level. Teachers would similarly be prevented from discussing the subjects with older students unless the subject is assessed as “age-appropriate” or “developmentally appropriate” in a manner not specified in the bill."
