You can make that the hill you want to die on, if you like. I wouldn't have instructed my kids to behave that way - to decide for themselves which laws probably are or are not constitutional, and follow only the ones they agree with.
Juries VERY seldom decide the law is wrong and the violator is right. Usually, in legitimate cases where the accused would probably be able to gain the sympathy of a jury, the prosecutor would have decided it's not worth prosecuting.
I REALLY don't want to live in a society where everyone kind of decides for themselves what rules they would like to follow and what ones they wouldn't. Honestly, can you imagine trying to buy groceries if most of the people in the store didn't think they had to stand in line, or didn't think they needed to pay the price on the item that was listed, or they only wanted one chicken breast so they pulled one out of the sealed packet, or thought they could drive their motorcycle through the store?
