The 13 colonies won their independence. You people lost.
Before they lost, the "secessionists" were whining about how they might be forced to work outside if they lost their slaves. They whined about how they might have to learn how to take care of themselves.
Of course, they lost. And, now you're whining about that.
Whining isn't the answer that you need.
If you are referring to Slavery, the Union recognized that "right", so this is simply a case of the pot calling the kettle black, and therefore without any moral force to it.
The 13 colonies won their independence. You people lost.
They asserted it, and the British gave in rather than risk all the death and bloodshed which would have been necessary to refute their assertion. Having asserted it as a sacred principle, you would have thought that same government would have honored it "four score and seven years" later.
Mad King George III was not as crazy as Lincoln. He stopped after 15,000 casualties. Lincoln kept pushing until 600,000 people were killed and trillions of dollars (relatively) were burned in an effort to subjugate people who wanted to be free of Washington D.C.
Of course, they lost. And, now you're whining about that.
If you are referring to my pointing out that the Union was the immoral aggressor that subjugated a people against their will, contrary to the founding principles of the Union government, and at great and tragic cost, as "whining", then I dare say your sense of proportion is seriously out of whack.
