Because there are not enough. There are never enough websites dedicated to classical Christianity. That is there are never enough until there is enough. And that will come in a few generations if the Lord wills.
For now, in a post-Christian, nay increasingly anti-Christian, America, the more sites, blogs and writers defending and promoting the cause of Christ, the better.
Well, maybe not necessarily better. Because these sites, blogs and writers need to be mature Christian writers, not blow-hards or unloving, poor-researched screeds. We have too much of that right now. But that is another topic for another post.
I hope that my writings are mature, loving and clear. If not, feel free to tell me.
