Actually it's Christian dogma that teaches we are all sinners beyond redemption, and that it's only through the grace of a loving sky daddy that it can be possible. 
Somehow, because a woman ate a piece of fruit, everyone thousands and thousands of years later are born into this condition of irredeemable sin. There is no logic to that being the case. It's magic. At least that is what the Bible states, however illogical such a tale is for modern ears.
To say you're required to fight for a statue that honors a man who helped kill 600,000 Americans -- 50 percent more than the number of U.S. service members who  died in World War II -- also is illogical. Or to fight the people you believe are fighting to take down that statue.
I'm agnostic on the statues, myself. And I had relatives back in the day who fought for the Confederacy on both sides of my family.
But I would say that whether the statue stays or goes in Charlottesville is up to the people of Charlottesville.
