The question is a fair analogical hypothetical since there are a slew of laws today which violate rights just as Jim Crow and others did in the past. You simply lack the moral integrity to give an honest answer because it would reveal hypocrisy on your part.
My position is the current position of jurisprudence in this country regarding juries and the Constitutionality of laws.
That does not change the incorrectness of your position. It is still wrong. Because the state says it's alright to seize somebody's property without due process does not make it right or just. But, it would seem that in your eyes it does.
Eminent domain? You don't LIKE certain laws; I don't LIKE certain laws. Overturning them in the jury box is quite another matter.
No. I would make certain to inform an Alabama court that I believed Jim Crow laws to be unjust. That would, most likely, disqualify me from jury service.
