I think I understood what PN meant, Lois; he said someone might be a white supremacist if they believe "those people wouldn't survive without our help", despite "those people" having been self-sufficient for many years.
Now for my own:
You might be a white supremacist if...you believe non-white asylum seekers should "go back to where they came from," despite the very real threats if they do so, but want open arms for whites at the slightest rumour of persecution.[cough, cough]Peter Dutton[cough, cough]
(Now I hope I've made myself clear.)
