You really believe those are good priorities for pro-bono legal representation when they can just as easily defend individuals and organizations that aren't actively promoting genocide and/or pedophilia?
Honestly, the worst among us are the ones that most need defense against the erosion of their civil rights because not defending them signals that those aren't rights that we care about and won't so much mind if they're taken away from us all
You get on a slippery slope pretty easily here. Just consider how heavily the Overton window moved in these last 10 years - what was baseline liberal in 2010 is often treated as right-wing to borderline fascist today.
