I absolutely agree - but it goes contrary to the domestic and regional(by that neighborhood) stance the current government of India has taken specifically w.r.t history of Muslims in the subcontinent.
There is precedent to try and right the wrong of history - but to squarely blame one party -manipulate and inflate historical events for political purposes just for feeding it as opium to masses in trying to cover up what were systemic failures to address issues - that goes against the idea of then trying to use a community as the entry point for an organization.
That is what I will leave it at.
The benefits of joining OIC are there - but then again smarter elements looking to sabotage it could exploit it and spread social media rumors on how this goes against Hindu tva ideals and basically lay it dead before it begins.
I really do not think right wing Hindu nationalist groups want India to be part of the OIC even though Modi might exactly do that.
Is the OIC the forum to address the abuses (real & perceived) towards Indian Muslims ? The only problem is that most of the governments are really bad abusers of human rights.
It is much less conflict for India to setup separate entities to conduct business with key OIC members. It saves Saudi Arabia and Pakistan a lot of the embarrassment.
I personally think Saudi Arabia & Gulf Arabs see threat of Indian membership to keep Pakistan in line.
