If I'm allowed to ask "What should we do about the Jewish Question" in a manner that appears civil, it's still not a civil discussion, regardless of the tone. If someone responds "don't you dare ask the Jewish Question," they aren't at fault for the lack of civility; the premise of the question was deeply uncivil.
Contextually, if someone on HN is asking "what should we do about the prisoners?" about people detained by ICE, the premise of the comment is uncivil. They are not prisoners, they have committed no crime (even by the standards of US law), and they are being held in deeply inhumane conditions. By any reasonable moral standard, the question is not "what should we do about the prisoners", but "how should we free people who are inhumanely detained." Allowing such an uncivil premise while banning emotional responses only reinforces the view that these people have committed some crime, and that they somehow 'deserve' the abhorrent treatment.
Furthermore, "concentration camp" has never meant "death camp", as many people seem to assume. I don't understand how it is incendiary to state they are concentration camps, when they largely meet the standards of a concentration camp.
I don't expect my posts to help these people, but I also refuse to remain silent about their inhumane treatment. If you still think this is inappropriate, I accept my ban, but I ask that you consider banning posts with such uncivil premises as well, even if they are written in an inoffensive tone.
