From 1861, the Indian Penal Code in India had a criminal law against "unnatural offences." This covered sexual behaviour between gay persons. It wasn't until 2018 that the law was finally changed to allow consenting adult behaviour in private. From 2009-2013 there had been some relief but the concession was overturned. So, it took another five years to get a permanent change, it seems. I understand this Penal Code now states that sexual orientation can't be changed; and I don't necessarily agree with that, but I believe people need freedom to make their choices. And criminal punishments aren't appropriate, in my opinion.
Even with a change in 2018, I believe adults in India--or those who have emigrated from there--may have some trauma from how they were previously treated? I believe we should have compassion for people; and we don't know what kind of personal struggles they've had...?
