It's also goes against one of those "commandments" they keep wanting to post in the public places as a way of imposing their morality on everyone else. Thievery in the Lord's name is apparently excusable, unsurprising given the ongoing evangelical support for the rapist in the White House..
These types already dedicate their lives to bearing false witness against their neighbors. What's one more commandment?
They take God's name is vain when they dismiss the Humanity of others; when they peddle hate and call it God's Will. That is their biggest sin, twisting God's word to make some love their fellow man less.
