Earlier quoted context omitted.
The whole LGBT movement and stuff wouldn’t need to exist if people were accepting. People aren’t. And still aren’t. When you actively oppress people for who they are, it’s not surprising it becomes more important.
Why do LGBT movements still exist in cultures that were/are very accepting of LBTQ individuals then? Alternatively: why are they completely absent in the countries that need them the most?
Do you have examples in mind? I can't think of a single culture that accepts LGBT as much as non-LGBT. Even ones that are somewhat close only became that way in the past decade or two.
> Alternatively: why are they completely absent in the countries that need them the most?
Because being identified as LGBT could literally endanger your life in those countries.
