That's false. Demonization is not relevant to any of this. Article 370 was a temporary provision in the Constitution. It's removal was on BJP's agenda since 80s

That's false. Demonization is not relevant to any of this. Article 370 was a temporary provision in the Constitution. It's removal was on BJP's agenda since 80s. India's founding founders like B.R. Ambedkar were also somewhat against having seperate set of rules for J&K. The most likely reason for it's removal is that Article 370 still protected regressive practices like Triple Talaq and Child marriage and created a beaurocratic roadblock in implementation of Federal Government schemes(like reservation). The claim that this was done to subvert state's Muslim majority doesn't hold merit. India has states like Punjab, Nagaland and Mizoram which don't have Hindu majority and are still doing well.
