By "modern" they mean "well before the Enlightenment", or as it says at the top of the Editor's page, "Because God Loved the Dark Ages". The publishers of AFM felt that the views of America's oppressed Christian majority weren't getting out, so the magazine was started just for them. By "just for them" they mean the extreme right edge of American Christian society, the edge that knows an appropriate Scriptural quote for any occasion but chooses to ignore the useless and foolish good bits like forgiveness and humility and instead focus on the "I'm chosen, so "F" y'all" nature of the Old Testament.
