Here, the ACLU is suing to prevent citizens from getting public records released by the government. From ACLU: "We have filed for an emergency Temporary Restraining Order and a Motion for Preliminary Injunction to prevent the disclosure of documents you have requested from the Department of Corrections."
This really blew my mind–I never thought I'd see the day when the ACLU filed suit to protect government secrecy against FOIA sunshine. This seems to be a clear conflict between progressive causes (in this case: letting trans-identified male people access female prisons) and supporting government transparency. Here the ACLU decided transparency could and should be denied because the information was being requested by bad people, or for bad reasons, or something.
If you only support free speech (or transparency) in cases where you agree with the actors, you don't really support free speech at all.
