First of all there's no unified voice of the Jews. And, even if there's some voice that says that bystanders are responsible, the question immediately presents itself, to what degree?
A guard shot in the direction of my grandma when she stopped at the railway station. She stopped because she heard people begging for water from the wagons.
What she could have done? And this is also very relevant for judging, let's say, Biden, or every head of state in general. People demanding action are usually completely ignorant of the actual agency of the targets of their screed. (And if they are in fact aware, then they are just demanding empty gestures, which is probably even worse, as it just makes more people mad.)
In general the biggest bang for the buck is voting.
Speaking up on Twitter is somewhere at the end of the list. Who knows where's speaking up when someone tells a joke with a punchline that is based some xenophobic/racist/bigoted stereotype. (Not to mention the complexity that comes from context, comes from the fun in safe transgressions against truly shared values, and so on.)
Of course there's an upside and downside to affirmative actions. Corporate mandated DEI bullshit is ... no surprise bullshit (eg. mandatory DEI training for everyone for no reason, just makes people fed up with the whole thing), but giving on the job training opportunities to disadvantaged people is not bullshit. (Plus also not without downsides and implementation challenges.)
