Potentially, but it seems to be more of a change in the western countries which have more individual freedom. The overpopulated developing countries don't have the open gay communities and gay pride parades like we do because of the lack of freedom. Instead they choose the safety of anonymity over there. Give them more individual freedom and they will also come out in numbers, same goes for most gays through the history of human civilization. Ancient Greece for example which was tolerant to gays, it had a substantial open gay community though it wasn't as over populated as for example some present day African cities which have smaller percentage of people who are openly gay. I think mostly because they are scared to come out.
