“All our efforts amount to nothing”
I wouldn’t say that. To me the obvious primary goal in life is to leave this place in a better shape then how you encountered it for the people that come after us.
If we truly take away the divisions in humanity (colour, religion, country,…) then there’s only one thing that remains: making sure we make it.
Love those around you and it’ll resound for generations. Clean up the planet and you just bought humanity a few more days if not years or ages.
It is NOT about what happens to us afterwards.
It is about what happens to them. The living.

At this point I feel the rpg culture should be firmly separated again from the mainstream only to have the mainstream stand between itself and this kind of awfulness.
