Liberals like Muslims see their goal as converting the world and judge morality as strengthening the position or increasing the influence of the ideology.
The Marx-O-Left controls the culture: Schools, The Media, Entertainment, The Arts, and many of the Churches.
Unless, conservatives start taking control of the culture the Marx-O-Left will eventually win.
Yet...I see little awareness , urgency, or concern by conservatives. Even here on Free Republic articles on the culture get only a fraction of responses that political issue of the day get.
