The Revolution was not secession from England. The colonies were chartered by England, but the tax power and local government was devolved from England at that time.
England was attempting to force the colonies to pay taxes levied in England where there was no representation, after taxes had already been levied by colonial governments, and was attempting to use military force to deny them rights like due process, rights to trial, and sent a military patrol to steal firearms. The port of Boston was closed by military action in an attempt to starve the citizens, absent any trial.
No similar unconstitutional acts were committed by the federal government before the insurrection of 1860.
After the insurrection started, the President declared that an insurrection had begun per the law of 1795, and the federal government successfully suppressed it.
The attempted insurrection was decided and found to be illegal in Texas v. White.
“No similar unconstitutional acts were committed by the federal government before the insurrection of 1860.”
Liar. You know damned well the north acted against the south and were preparing to wage war against the confederacy.
