People are posting furiously, but anonymously, on Bailing Water.
Most of the posting about Lutheran doctrine on the Net is either done anonymously, through secret email lists, or on closed blogs.
No one wants to risk the wrath of the apostates, but they should be afraid of our wrath (more significantly, of God's wrath). As I recall, Robert Preus published in his own name. Jack Preus published in his own name. Marquart published in his own name. When WELS had problems with Missouri liberalism, they organized public forums, not secret meetings.
The timidity evident today comes from a lack of faith in God's Word, in His Promises. The timid trust in the mighty synod pension plan, but not in God's power. The timid love their beloved synod, but they scorn God's Word. The timid say they love God's Word, but in Jerusalem they whisper low the name of Lutheran Confessionalism - lest it be heard on the streets of Gath (2 Samuel 1:20; Schmauk).
God does provide. His Word never fails.
I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread. Psalm 37:25 KJV.
