Like others, I think that this is not so much racism, and more to do with different cultural norms - the vast majority of the footage will originate with Indian photographers and news media, who have a very different reaction and relationship with death. The UK has a very uptight and sterile view of death which is actually rather out of step with many other parts of the world. In the UK people die in sterile surroundings and are whisked away, often never to be seen again, and if they are, in a bland "cosmetic enhanced state" that masks death and its realities. That is "wrong", but it certainly isn't the way many parts of the world operate.
The other aspect to this is that one needs to bear in mind that all media is politicised. Whether or not someone is to blame for XY and Z (insert your own version of what people should or should not have done) India needs help. They know, the media knows, and we know, that the fastest way to get the world to respond to that need is through imagery. That is why, in the wake of disasters or poverty, reports focus on images rather than words. Words tell people what has happened, but seldom import the gravity that an image does. Tell us that 45% of the population do not have enough daily nutrition, and that is possibly an interesting fact but tells most people nothing. If they read it at all. Show us a picture of a rake thin mother and a severely malnourished two year old, and our purses spring open.
Right now India needs medics, equipment and supplies. Those pictures are forcing people, and governments, around the world to see the reality of their lives at this moment in time. Basically, it is forcing the world to do something. Indians themselves are far more likely to be sanguine about bodies and death and such images. For many of them, coronavirus or not, this is their daily lived experience, just compounded by the weight of the situation.
