In list form.

The battle is now cultural.
It is not political. Attempting to use politics to put forth a weak form of Christianity is a total failure.
It is not spiritual, in the sense that we need to get on our knees and pray hours per day. We are over-watered by prayer. 
It is not negative. We do no one any favors by telling people not to be gay. 
In fact, Christianity has become a “not” religion, not offering things but instead prohibiting them.
This should not be.
The solution is to be both positive and creative.
Positive, in that the benefits and aspects of being a Christian are shown.
Creative in that Christians make art.
No more endless criticism and fawning over why Harry Potter is secretly Jesus.
No more “art as another means to say no.”
No more of these three things: abortion, homosexuality, persecution complexes. 
Art as a way to say yes. Why are you a Christian? What does it mean?
Art must be made. If you cannot make, you support and sponsor.
To make art, you must be intimately involved with it. 
You cannot run into your little homeschool prisons, only read your Tolkien and your Lewis, and create things from a cramped mind.
You must read widely and live wildly. Drink deep of art, and also Christianity. You must face the size and shape of the world.
If you sponsor and support, it should be of love for the thing itself. Support or be a patron for the art you love and want to see more of, not for the message you want to send.
Realize you will have to do this in spite of other Christians.
The Christian cultural gatekeepers are corrupt and word-seeking. They care about secular admiration and money. This is why Christian fiction has become bland Amish romances for grandmothers, and why Christian intellectuals have been absolutely useless.
You will die for you art on unknown hills. Both Christians and nonbelievers will oppose you.
But in the end it must be done.
Why? NO ONE ELSE WILL EVER DO IT.
In the end, it’s just us. Now go out and do it.
