I write this as someone who saw through Modi long before anyone in either country recognised him as a threat.
You are broadly right, but only broadly. Unfortunately, you display the usual Pakistani trend of taking an apocalyptic view of India's present and future, irrespective of when in time you take the view: it is invariant, and it doesn't matter whether you are looking at 1950, 1960, 1970, 1980, 1990, 2000, 2010, or, now, 2020. The expressions of concern that I hear now ring hollow against the background of the pitched hostility at all times in the past; it never let up, what difference does it make if it is couched in terms of the end of days now? It was always pitched like that, among 'green' bhakts, although there has always been a counter-narrative in Pakistan, a stream of thought that Indian liberals of my sort clung on to in spite of the overwhelming evidence to the contrary.
Coming to the details, if you have managed to hold on till now, the Modi formula was not and never will be universal. 'You can fool all the people some of the time....' and so on. It is visibly not universal even now. If you will not take the trouble of wading through the gallons of nausea-inducing garbage in the air-waves - and who can blame you? - you will never get to understand the limited support initially, or even that it was in fact limited, or the subsequent growing disillusionment. Unfortunately, even the most thoughtful Pakistani is apt to first fall prey to feelings of righteous indignation, and then, and only then, to look at the evidence - by which time it is too late.
I haven't seen the discussion to this point, and this comment is to be seen in the mouth of an observer who has been focussed on what is happening on the ground, and has not really been looking at the discussions on PDF. You will forgive me for for any broad-brush strokes that I may have fallen prey to.
