Humans throughout history have formed all kinds of activism. Starting way before Jesus Christ started his activism.
In modern time just the past hundred plus years you've had Native Americans advocate for their choice to live as their culture encourages, Women activism who fought to have voting rights--- to turning the justice system to work for them and against men, to Martin Luther King, to today's woke-ness activism, Black life matters, and much-much more.
I personally don't see the human race continue for much longer, thanks to the idiots who invented the Atomic Bomb.
It's only a matter of time before some craze lunatic, or "Human Error" starts a nuclear war and all that activism come to a quick stop.
In the meantime, work hard at getting all the enjoyment out of life that you can before it comes to a brutal end.
