Do you seriously contend that cotton taxes passed in 1861 and later were the cause of secession?

Didn't help. The cotton tax was 1% per pound, not insignificant. Morrill Tariff was a greater contributor over cotton taxes.

The cotton tax was one cent per pound, not 1%. It was a war tax that went into effect in October, 1862.

Do you seriously contend it was a contributing factor to southern states seceding in late 1860 and early 1861?

That tax was passed by Congress 1 July 1861, after the war had started.
