Yes, because being a bigot against homosexuals is remotely similar to thinking the legal system is unfair and unjust.
If this were reversed, and this guy was an LGBT-ally who supported a clerk who was giving out SSM certificates illegally, and he had the same thing happen to him, I’d say he was a hero and the punishment unjust. And I’m pretty sure I’d have a lot of supporters here.
For some reason, legalists seem to think this is a flaw. But it’s not. I don’t hold the law to be the epitome of virtue. The law can inform what’s right and wrong, but it’s not the be-all end-all. And that’s why maintaining the right of nullification is important.
Until we have a system where no innocent man goes to jail, there will always be a need for nullification. And I am free to argue what I think would make the system work better.
