It speaks volumes about you though, standing up for a racist acting "upon his principles".
Jeez, if he wants to "act upon his principles", he can do it on his own time. Send him back to his porch to yell at the colored folk.
Thankfully people like you are not in charge. FreeRepublic scares me sometimes. 99% of the time we're a bastion for freedom, and then every now and then people like you show up longing for Jim Crow.
JPs are not paid by the taxpayers to perform wedding ceremonies; it is not a required duty. He did not prevent their marriage and even arranged for someone else to take care of them; he simply could not take their money to do something he didn’t agree with. Perhaps you could dredge up an ounce of understanding on that point, even if you don’t agree with his reasoning, as I don’t (and stated so previously, although you chose to ignore that in favor of throwing a Jim Crow accusation at me).
Beware of a surfeit of righteous indignation based on how you think an anti-racist should respond to a situation; it can mask a form of political correctness while it stomps all over freedom of conscience.
