Also the person the quote is attributed had some abhorrent views most people who share them have the good sense to only vaguely alude to through veiled references to Ayn Rand and questionable race science articles. He was not exactly a defender of democracy and equal rights.
The defense he's speaking of isn't in saying the scoundrel isn't a scoundrel, it's against the oppressor. That's why he still called them scoundrels.
