No, this is common in most liberal "mixed" couples, surname is ofc the husband's, so first name is chosen by the wife as per her tribes' names.
Like you have Aditi Rao Hydari, a total bomb of an actress with 10/10 looks, father is Muslim, mother is Hindu, name is beautifully mixed.
Kamala and her mum do not care about our "shithole" country or the "backward" religion here, a name means nothing, fake jhumlas, interviews and soundbites for votes from Indian-Americans also mean nothing.
If you mean (((Christians conspiring to fool hindus ))) it's not that, atleast not here, most Indian christians like to keep tribal connection either in name or surname, except the totally westernized ones like Goans.
Tribalism is a very strong force in a "normal" environment like in India, however in the West it doesn't matter, there is no tribal solidarity like your see in Kamala or even full blooded Indians there, like there is that infamous democrat woman called Pramila Jayapal who keeps shitting on India about hooman raitas.
