This measure would be purely symbolic.
According to an article by the Associated Press, Assemblyman Michael Patrick Carroll, a Republican, is not in favor of the bill. He said, "If slavery was the price that a modern American's ancestors had to pay in order to make one an American, one should get down on one's knees every single day and thank the Lord that such price was paid."
In other words, according to Assemblyman Carroll, the blacks should be thanking the Lord for the fact that their ancestors were slaves, because that's how they came to be Americans. If not for slavery, they'd still be in Africa. Praise Jeeeeeesus!
