You’re the one who is morally confused, and uninformed to boot. Give me an example of an “unjust law” that you would nullify as a juror, violating your oath.
1) Defending you home, life and loved ones using deadly force
2) The right to bear arms and defend yourself
3) So-called hate speech crimes
4) Rights of a property owner to decline to perform a gay wedding in their establishment (coming our way in IL)
5) The right to free speech as posited in the article posted in this thread
6) The right to grow your own food for your own consumption
Hell, I could go on all day but I think the point is made.
