Your assumption is that mass pogroms were possible, such attempts would've lead to massive revolt and unification of all hindu ally's and perhaps Mughals losing power. Having said that in Afghanistan, Pakistan, Kashmir, Iran ( which was Zorastrian ), state discrimination and oppression of Zorastrians were used.
Again that doesn't mean all Indians converted through sword, but discrimination was a tool, jizya, and even extreme oppression. India has more Zorastrian than modern day Iran, more Sikhs, Jains and even countless Tribal religions. All other neighbouring countries which had Islamic rules have either a dwindling population, or nothing left.
It's again complex, yes to some extent Mughals were colonisers but they eventually simply wanted to rule. It's not discussed because most history before 11th-13th century was systematically wiped out over centuries.
Pakistan and Afghanistan have little to minorities or even the memory of past left, but that's mostly what happens with cultural imperialism. There were Hindus / Bhuddist or Zorastrian in those areas, now there are none. Infact India have more Zorastrians than modern day Iran, many fled to India around 16th Century escaping similar cultural imperialism.
That's nuanced, they were always challenged every few decades, from Marathas to Ahoms in North East. Fighting with all Hindu princely state instead of making them ally would've surely might have been counter productive. While it was their intention to Islamise, and many did, but it was impossible without an extremely cultural backlash that they also feared.
Mughal empire was collection of many wealthy provinces, which were wealthy even before Mughals. After assuming power most Mughal ruler did nothing but wasted wealth on countless vanity projects, unlike Europeans where rulers still funded exploration and innovation.
There are a lot of architectural marvels in India from Sun temple to Ajanta and Ellora caves and Kailasa Temple. I personally never understood why more was not written about them, very few know about them.
Mughals never ruled India for more than 200-300 years, and were challenged by many regional players including Maratha's.
India has far more to offer beyond Taj, and I would say if not more equally interesting architectural marvels like Kailasa temple.
Racist much? I work out of Europe and manage teams both in India and Europe. My experience have pleasantly gotten better with Indian teams. If the quality is sub-par then perhaps you're not a good manager? perhaps failing upwards?
I don't think China is doing as well as many Chinese might believe but this doom of China is predicted every other year. Chinese companies are making strides in battery tech ( CATL ) and robotics ( DJI, Siasun )
