One time when I was on a grand jury, I tried to convince the other jurors that we don't have to send people to jail for marijuana. It's stupid and unjust, and we can just say no. They don't make you show your work. (Yes, on a grand jury the prosecutors can just try again, but it wastes their time.)
Those half-awake bootlickers weren't having it. "We have to do what they told us!" "What, are you a dealer?" "The law is the law. Call your rep is you want to change it."
Maybe an ad campaign would move the needle, but there are a lot of stupid, selfish, people out there ready to lick the boots.
Maybe, but they might also say something like "Right. They followed the law and jesus was crucified, saving everyone." There are probably religious arguments to make, but religion (at least christianity in the US) is often just emotional slop.
