Earlier quoted context omitted.
I would say the ACLU is by definition anti-government, though. Not in the sense that they want it destroyed, just in the sense that they'll always be the opposition to the executive branch. So they're "anti-Trump," but not in a way that's easily politicized; if any Democratic executives tried to punish people for being pro-Trump, the ACLU would be against them too.
> the ACLU is by definition anti-government I'd rephrase that as "in favor of the rule of law". Governments break the law all the time and need some form of checks and balances to correct wrongdoing.
The ACLU will fight against laws it considers unjust, illegitimate and liberticide. It has under pretty much every administration.
