How our history was changed

We are taught in schools and colleges about our own history, traditions, religion and culture in very disparaging terms amounting to denouncement and shaming rather than any genuine criticism. Let me give an example in current history. We were taught in our class two, yes, 2nd standard social studies book that "Gandhi ko ek Hindu dharmandh ne mar dala". Now can someone tell me what's the need of adding Hindu and dharmandh upon that to Gandhi murder? I, as a child 6-7 years old asked my parents and teachers too about 'Hindu dharmandh' but no one gave me a satisfying answer. It riled me then as a small child that something is wrong with that phrase when i did not even know the meaning of 'dharmandh'..! Now lets move to medieval and early modern history. Its replete with all kinds of negative and unspeakable things against Dharma in general and Braahmanas in particular. Yes, there were serious aberrations but only Hinduism is a religion in the entire world which is abused for aberrations its followers may practice even though it has no sanction for in the actual sacred texts. Braahmanas/priestly class were/are criticised heavily and the references are those of: Al-Biruni, Barani, Firishta, AbulFazl, Jordanus, Francis Xavier, De Nobili etc who were representatives of invading rulers at best and themselves cunning,fanatic & cruel ghazis/missionaries at worst; obviously they will demonise the biggest obstacles to their path which was,is and will remain so. And its happening even now. Britishers and communist historians later on found it very convenient to propagate the fabricated lies and biased untruths to their own advantage. Let me put, for explanation sake, this implausible but converse way: suppose i am a zealot dogmatic fanatic Hindu missionary aided by a conquering army to Arabia/Europe..we have defeated their sultans and kings but are having only partial success in converting those people to my faith..who will be my enemy number one? The defeated sultan/king or the conquered masses or the mullah/bishop who preaches and holds real authority over their faith and people? Obviously it will be the mullah/bishop who needs to be demonised and discredited using state machinery so that their faith is weakened and their religion is broken down and thus paving an easy path for my faith to be accepted by their masses as a new hope or at least to be seen in a favourable way. This is what has happened in India Bhaaratavarsha for more than last 1000 years and its still happening:under the Nehru dynasty,that we are being taught history and social studies written only by foreign invaders ie ghazis,missionaries and communists.
