You're falling for, and perpetuating, left-wing propaganda.
The bill doesn't prohibit "saying gay".
The bill prohibits discussing sexual orientation. Straight and gay alike. Personally I think that at those ages basically all discussion of sex should be off limits (except strictly in a biological sense "this is where you pee" or "naked boys look like this drawing and naked girls like that drawing").
Also your argument is a nasty bait-and-switch. Your original comment was about "limiting freedom of speech of teachers is bad" but then you switched to "of course we should limit freedom of speech for teachers, but not in this specific case".
