Sadly, the guy hasn't even flinched. He keeps spouting back.
One responds: "How can anyone compare the genocidal atrocities of Nazi Germany to what's happening now?" He answers "Wasn't hard, really. No effort at all."
But then another points out: "Other countries monitored their citizens’ phone calls under the guise of “national security.†One such group was called the Gestapo. Another the NKVD. A third was run by YOU. Comparison hurts, doesn’t it?" He claims that's a "faulty analogy." As if comparing this to gas chambers isn't?
Then again, he admitted he tweets while drunk.
