How are wars won?
To win a war you don’t need to kill every soldier on the other side. What you need to do is destroy the other army as an organized force. You destroy the ability of the officers to command and the morale of the men. You destroy their perception of the worth of their side and of their own self-worth.
All wars are culture wars. To win you must destroy the values of the other side. (That is one reason why we’re losing to Islam no matter how many times we beat them on the battlefield.) You must destroy their sense of purpose and the values instilled in them to break them as an organization.
That is what the left has been doing to us.
