My initial reaction to reading about Barr makes me want to agree with you. However, I really haven't looked into him too much - tbh I only really know about him from popping up in HN articles (where he is always cast in a negative light). Any chance you have some links relevant to his history of violating civil rights, etc? Would love to be able to read through them to form a stronger opinion myself.
ACLU is one here listing many of his outright struck down ones including sticking Haitain asylum seekers in Gitmo indefinitely. And that is restricted to the obscenities that the courts have called out instead of accepting as the norm.
My personal philosophy is civil rights are not up for a debate or vote. Normalizing them is itself a form of damage that mere politeness can never justify.
