I agree each one of those things was silly. So were the couple of examples I gave you. You have to browse the threads around here to realize that pretty much every team's supporters react similarly to similar issues.
Yes, Indians are a more numerous and more passionate bunch when it comes to Cricket, and hence you see all those funny incidents of making a mountain out of a mole hill. But the small minority of supporters from other countries behave no different, they just aren't numerous enough. What you and others want to infer from these reactions about the culture of a whole country, and why it's so important for you and others to spend so much energy trying to figure out psyche of Indian fans is equally amusing to you.
Yes there is a lot of hero worship in India, I fail to see however why it should
bother you so much as though it's the biggest tragedy the world is facing 
I am even willing to have a serious discussion on why there is this level of hero worship (has to do with socio-economic context IMO), but I don't see any seriousness among people happy to generalize and criticize.
And there is hero worship in other parts of the world too. The crazy amount of love for late Michael Jackson is a case in point. So that's that. Trying to generalize and paint one entire nation (one of the largest and most diverse one at that) with the same brush only tells me you have no serious point to make.
