Your concerns are valid. I am out of touch with how these topics are currently taught in elementary and middle schools. So, I googled it for California. I first read What is Comprehensive Sexual Education? and some of the claims there about what is being taught in schools are disturbing. Then, some more googling lead to this FAQ for Sexual Education, HIV/AIDS, and STDs - Comprehensive Sexual Health & HIV/AIDS Instruction (CA Dept of Education) which is the CA Dept of Education's official website. I read through all the 21 questions there. The "opt-out" strategy rather than "opt-in", teachers need not be specially trained, the name-sake vetting of outside speakers, and how the medical facts are checked before being taught to the students -- all these left me shaking my head in disbelief. The CA law requires CSE to be taught in grades 7-12. For K-6, it is left to each school district to decide. So, a bunch of tenured school district staff have full control over what is the "age appropriate" way of teaching all these topics to kids under 10-11 years old. Good Lord. What should Indian parents do? Read up good quality balanced opinions on both sides of any debate. Research. Get to know the many terms, acronyms and definitions around LGBTQ, gender identity etc. Be aware of their rights such as all the materials used in schools have to be available for parents to inspect. Don't blindly believe that the school and teachers have the child's best interests at heart. I used to think if I vote Democrat, pay taxes, vote regularly, check the child's Friday folder, read the newsletter, sign all forms in time, I am good. Had some rude awakenings. Above all, develop an atmosphere at home where the child feels comfortable to come to parents for support and answers. There will be times and years when the child trusts their friends more than parents, but always keep the lines of communication open. For the record, I consider myself very pro-LGBTQ, was shamefully ignorant about the gender identity related concepts and educated myself on those and have come to respect those. But, legislation that these topics should be taught in publics schools in this manner is giving untrained teachers too much influence over highly impressionable young children, IMO.
