Ain't that the truth!
Christ Our God (and Our Lady "Notre Dame") want a sanctuary to, in her words, "magnify the Lord." A temple of living stones, the "pierres vivantes" of Paris. And if they, the pierres vivantes, wish to build a magnificent jewel of architecture in His name, and to honor His Holy Mother whom He Himself loves and honors, then God be praised.
But a historic restoration honoring "our diversity" for the glory of France? That would be an idol. Even the Muslims know that.
