The historical origin of the term is one thing, the historical associations of it are another, and it's not possible for people to argue about it on the internet without flamewar.
The HN approach is to observe that we don't need to go there, and then not to go there.
I understand that you don't want to use the term "concentration camp" because it's associated with Nazi extermination camps. What term would you prefer instead, "internment camp"? There really needs to be a term which people can use to describe sweeping up classes of people and confining them to an area.
Yes, that is a more neutral term, for the reason you mention—but only if it is used where strictly accurate, and not as an exaggeration to score rhetorical points. When I looked yesterday, it wasn't clear to me what's actually being proposed at the site the GP was linking to. If it really is a proposal for involuntary confinement, then the word internment seems justified, otherwise surely not.
