Those are things you said, not him. You uncharitably read an absurd statement of equivalence where he merely made a comparison.

The refusal to see parallels or accept comparisons to dark periods in recent history unless they are 100% equivalent is a disease that threatens our ability to learn lessons from the past. If we only accept comparisons to the Gestapo when they begin gassing people en-masse, then it is too late.
