No, any instruction about heterosexual marriage or romance is banned by the bill. Also banned? A 1st grade teacher telling their student (with two gay dads) that their parents are sexual deviants who are going to go to hell when they die. Do you feel that if a teacher felt like teaching that to their students they should be allowed to? How about if a teacher felt like teaching it's 2nd grade class that a man having three wives is perfectly normal and if their parents don't agree, they are bigots?
This bill is well-designed in that it simply states that a teacher should not and cannot provide instruction on any of it because it is not appropriate for children of that age.
