Good thing America doesn’t currently have a gestapo and concentration camps. All thanks to the restorative power of violence.

Unfortunately the pro-slavery forces rallied during the period of reconstruction, and were able to transmute slavery into a system of mass incarceration. Opposition to that wasn't non-violent, but you can't blame oppressed peoples for not always winning their confrontations. You can read about that in WEB dubois's black reconstruction in america. Your unwillingness to read even short articles above, is probably why you're so ignorant of the history of these class struggles.

Things have in no way escalated since then,

This is interesting coming from someone who avows pacifism, and thus thinks that reactionary violence shouldn't be challenged in any threatening way, and that we shouldn't dare fight back.

Anyway, you can keep offering Gandhi's advice that "jews should've offered themselves to hitler's knife, as it would purify them". But the rest of us in the real world know that when someone attacks you, the best course of action is to stand up and fight back.
