I don't think there is a word for gays/lesbians in Punjabi. Gandoo is like a slang word that is used as an insult rather than an actual word for gays.
Older punjabis here call gays kusre. In Pubjabi gays and trans are kusre.
This "preist" has been doing this for far too long now, remember watching his videos like 10 years ago aswell.
This stuff is only going to increase and get worse, this is just the beginning!
Far to many ultra liberal people within the community now. I'd say around 50% people in the community are not against this or interfaith marriages etc so I don't think there is much the other half will be able to do.
