No, you need to expose them for many reasons, accountability, make it harder for them to join. You questioning this makes me think you agree with their tacticts, and it has been extremely obvious that organization is a total mess of rule breaking.
I’m not defending ICE. I’m questioning the logic. How does doxxing create “accountability” or deter recruitment unless the implied consequence is that someone might use that information to harass or harm them? If that’s the deterrent, we should be honest about what’s being encouraged.
Fascism, contrary to many people's usage, has an actual meaning that is not "things I don't like".
One definition:
"Fascism is a far-right, authoritarian political ideology centered on a powerful dictator, extreme nationalism, and the nation's interests above the individual, suppressing opposition through force, propaganda, and control over society, business, and labor, often promoting militarism and a strong, unified national identity."
Note that "citizens doxxing government actors" is not in any way an ingredient of fascism.
