Central Board Of Secondary Education [CBSE] — Absurd chapter in our english textbook

I am a student studying in 11th class. I have a problem with a chapter in our english textbook (snapshot). The chapter no. Is 3 and its name is "Ranga marriage"
Now 1) what are we supposed to do by reading anyone's personal life? How is it goin to be helpful in our future. Though it was surely mind disturbing

2) what is basically the aim of this chapter? In the chapter where ranga is talking that how he will not marry a girl younger than him, who wants to marry a mature and right girl, ends up marrying a girl of 11 year old. How? Because the writer makes that 11year old innocent soul sing in a room, call ranga, ranga hears her voice and gets seduced by it.

Now he starts to see a 11year old as his wife and whole chapter further glorifies their romantic relation.

3) This now is not enough, the girl also gives birth to a child at the age of 11.
The writer wants ranga to marry a girl of 11, and thats why he want both of them to meet and know eachother and is also sucessful in this mission . In short this book glorifies child marriage.
Ranga being educated was expected to show a mature behaviour, but he didnt give a second thought on impregnating a girl of 11

4) i play with my 11year old sister, who actually thinks that male makes boy babies and female makes girl babies. And here you not only elaborated
on how a child of 11 got indulged in SEXual activities before hiting puberty but also glorified it by writing their sweet romance in the chapter.

5) how can you even expect a 11 year old to even know what "love" is? Why are we expected to learn this ### and write it in our exams, whats the point behind this? Can you even imagine how mind disturbing it can be to read these things in a school textbook? Is this our education board up to signifying how a 25 year old married a 11year old girl?

I would request Cbse to delete this chapter and add any other chapter at this chapter's place.
I will be grateful if steps are taken on this, because these things are extremely mind disturbing.

Thanks and regards.
