Someone wrote a well done article (I wanna say it was Medium) which appears to be what the stackexchange answer is summarizing that actually tracked down all the who said what and laid a pretty darn good case for why the quote wasn't legit. It basically boiled down to the guy who alleges the quote having several past opportunities to drop that bomb but instead waited until everyone who could disagree was dead. A cursory Google search didn't turn it up for me and I'm not letting a stranger on the internet suck up any more of my time.
