This is a completely human response to the horrible things happening the world both domestic and abroad.
It’s also history repeating itself: doing nothing when bad things are happening in our communities is what allows them to happen.
Think what the villages around the concentration camps must have known and yet did nothing.
Sure you could just focus on tech. You alone can’t stop Donald Trump or Stephen Miller from their racist move toward autocracy usurping norms and the world order … but you can join in with others who are trying to make a difference.
Apathy is a human emotion to such dire things. But we are better than that.
If you mean extermination camps, they knew. They were also part of occupied, conquered and heavily terrorized lands. They occasionally did something, terrorist attack against Germans here and there, usually retaliated against by killing a lot of random citizens. Usually motivated by plight of own people.
Extermination camps were located in Poland - German plans involved moving away and killing all Polish, so that they can be replaced by Germans. Germans seen Jews as primary danger to be exterminated fast, Slavic as secondary lower value being to be exterminated slowly in time. Polish army lost the war. And random villagers were not in position to do anything about the highly violent occupying army.
(And yes, Jews were at danger of being denounced by anti semitic locals too. Turned out one could be subject of racial oppression and being oppressor himself).
