Answer

The mainstream media and the academia have been dominated by people, often called the Eminent Historians who are against any historians who debunk the pseudo-secular myths fabricated in the last few decades. 

Historians like Goel published on topics which are considered absolute
taboo  by the mainstream media. They openly criticized Islam, Christianity and  communism. Goel criticized Indian secularism, alleging that "this  concept of Secularism is a gross perversion of the concept which arose  in the modem West as a revolt against Christianity and which should  mean, in the Indian context, a revolt against Islam as well. [Link]

Historians like Ram Swarup and Sita  Ram Goel objected to the re-writing of history by the Marxist historians  of AMU and JNU. Goel called it "an insidious attempt at thought-control and brainwashing" and argued that the NCERT guidelines are "recommendations for telling lies to our children, or for not telling to them the truth at all."

They presented their work without any kind of self imposed censorship.  That made it difficult to swallow for Marxist/pseudo-liberal leftist  pseudo-intellectuals.  Historians who don't want to whitewash the  barbarism of Islamic invaders are seen as threat to the Eminents'  ecosystem of lies, and hence they are subjected to all sorts of   viciousness to malign them by ad-hominem attacks (e.g. calling them  Hindutva historians, fundamentalists, hate mongers, RSS people etc.)

Notable works:

SR Goel and Chandmal Chopra: The Calcutta Quran Petition (1987): The book dealt with censorship, the banning of books and the Quran. It chonicled the events around a petition to ban Quran.  What can be a more blatant disregard for political correctness! It's an interesting book that exposes the pseudo-secular discourse and how ruthless Islamic intolerance is towards any criticism. The book: [Available Online]. The wiki page is here: The Calcutta Quran Petition. 

Chandmal Chopra tried to obtain an order banning the Koran, by filing a Writ Petition at the Calcutta High Court on 29 March 1985 as the Quran "on grounds of religion promotes  disharmony, feeling of enmity, hatred and ill-will between different  religious communities and incite people to commit violence and disturb  public tranquility." He also included a list of several dozens of Quran  verses that "promote disharmony" in his petition.

Chandmal Chopra was arrested and later released. Goel had to abscond to  avoid getting arrested. However, it must be noted that the authors write in this book that they do "not stand for a ban on the  publication of the Quran. We take this opportunity to state  unambiguously that we regard banning of books, religious or otherwise,  as counterproductive. In the case of the Quran, we believe and advocate  that more and more non-Muslims should read it so that they know first  hand the quality of its teachings."

* Ram Swarup: Understanding Islam through Hadis (1982):   It was banned after remaining 8 years in publication. There  was a  criminal case against Goel for printing the book, the case was  dismissed  in 1997, but the book still remained banned. [Available Online]

* Ram Swarup and SR Goel: Hindu View of Christianity and Islam (1993):   Goel and Swarup went into hiding because they feared that they could get arrested after a ban was demanded on the book. The court accepted a bail.       [Available Online]

* How I became a Hindu [Online]

* Heroic Hindu Resistance to Muslim Invaders  (636 AD to 1206 AD) [Online]
The Story of Islamic Imperialism in India [Online]

* History of Hindu-Christian Encounters (AD 304 TO 1996) [Online]

* Hindu Temples: What Happened to Them. Vol.1 [Online] and Vol. 2 [Online]

* Freedom of Expression: Secular Theocracy Versus Liberal Democracy [Online]

These  non-mainstream historians were discriminated against by the Congress  governments too. Goyal, interestingly, was a staunch Marxist in the  beginning, and was critical of Congress and Nehru in his articles. When  Goel wanted to apply for a passport in 1955, he was told that his case  was receiving attention from Jawaharlal Nehru himself, and his  application was not granted. He later turned to anti-Communism. [Link]
