The misinformation era means there's a gulf of frequently incorrect assumptions about what the Federal agencies actually do.
I mean, what if Congress created them to be unaccountable? Then both things would be true!
these are very different situations, and it appears you wish to defend the motte and get the bailey for free?
I never said all government organizations are unaccountable? Just that (practically-speaking) some organizations are unaccountable because they rarely (or never) are called to account by those who are supposed to hold them accountable. This could be due to them simply being a low-stakes organization that demands very little attention, for all I know!
Interesting that you call out a specific fallacy whilst bringing your own strawman into play!
Does that imply unaccountable, or does it mean Congress thought they were doing a good job?
