A 2023 Pew survey found 53% of Indians being for recognizing same sex marriage and 43% against (for comparison Switzerland in their 2021 referendum had 64% for and 36% against same sex marriage).

India relatively recently decriminalized gay sex and passed a law legally recognizing the gender trans people choose to identify as, and the national health insurance covers abortions and transitioning.

Its not as simple as your comment makes it out to be, equality in marriage might sometime be recognized.
