Satanists want to erect a monument beside a Ten Comandments slab

The Oklahoma Capitol had a monument had put a monument of the Ten Commandments in 2012. Well the thing is that now Satanists are appealing for religion tolerance and want to place a statue of Satan next to the Ten Commandments. I know that people have freedom to choose their religion, but as a Christian to me it is offensive to put a statue of the devil right next to a monument of the holy law of God. If Satanists want to put their idol, at least they should respect that Christianity and Satanism are totally opposite religions.
