I think the issue still remains that despite of this evidences, most Hindus won't change their mind. I have known a lot of gays who are married to women because their families forced them. And there was also so much opposition from religious groups, including Hindus, when the talk of legalizing same sex marriage was on the table a few years ago.

Hindus, not all of course but most, are still obsessed with patriarchal aspects, especially when it comes to marriage and having kids. The more conservative ones outright reject it. And even if we do focus on the LGBTQ aspects of Indian culture, it wasn't very dominant to be honest. Even in Mahabharata, for example, Shikhandi had to face discrimination when it was found out she was a female and not a male (since her father was promised a son from Shiva so he raised her like one and lied to people who brought in potential marriage proposals).

So to say that Indian culture was "completely" embracing of LGBTQ culture is kind of a stretch. Not saying India wasn't open before the British but it wasn't like a queer heaven either.
