I have enough experience with these history texts since that is one of my favourite subjects.Did you check 7th standard social science text in Kerala?If didnt you should that.
In history part you can see elaborate explanation of invasion of the central Asian and Afghan Muslims.One of them Muhammed Ghori and Privthiraj Chavan fought against each other.Ghori did two attempts and he decisevly defeated in first 2attempts .In first time he even captured by Prithivraj but that good and honourable that invader.Ghouri repayed his tribute in the second attempt by ripping Prithiviraj eyes.
But these text dont even mentioned about.Forget about cruel part since childrens dont need to know about such violence .But these 'sickular' text ignore to mentioned the great heart of the Prithviraj Chavan.
Any student who learned or any teachrr who taught them cant understand that cultural difference .The real tolerance and honourable culture of Hindu kings .
That is where your secular leaders failed our tradition ,nation and culture.
