I think it's more a result of American cultural hegemony than religious conservatism. The anti-LGBTQIA+ culture that dominated most of the 20th century spread around the globe and especially to places where US imperialism had a strong foothold. Now de-colonial and anti-imperialist movements reject this cultural hegemony as it becomes more inclusive of these groups. They're rejecting an undoing of this chauvinism without recognizing that it was this same cultural hegemony that created it in the first place.
