That is false. Your so-called source also gets its stats wrong. The first confederate tariff was to adopt the 1857 US schedule.
When I read these crazed rants I am often reminded of a Doonesbury cartoon of years ago, where Duke's assistant Honey has to go back to China and testify at the trial of the Gang of Four.
The prosecutor asks Honey, "Which is it, Ms. Hsu? Were they merciless oppressors of the workers or doggish lackies of the imperialists? You can't have it both ways!"
That is the way the neo-rebs play out their little "heads I win, tails you lose" fantasy.
