Or you could just teach the TRUTH about Luther - at the very LEAST in Lutheran Colleges and Universities - so the "teachers" called from them might not get blind-sided when some enterprising (Luther-regurgitating) student stumbles upon the same TRUTH using Algore's Interweb thingee.

"We are at liberty to be real, or to be unreal. We may be true or false, the choice is ours. We may wear now one mask and now another, and never, if we so desire, appear with our own true face. But we cannot make these choices with impunity. Causes have effects, and if we lie to ourselves and to others, then we cannot expect to find truth and reality whenever we happen to want them.
If we have chosen the way of falsity we must not be surprised that truth eludes us when we finally come to need it!"--Thomas Merton
"The right to search for truth implies also a duty; one must not conceal any part of what one has recognized to be true."
--Albert Einstein
Then again.... maybe the "standard" keepers aren't so enthusiastic about that whole "TRUTH IS GREAT AND WILL PREVAIL" idea which, coinkidinkly, didn't seem to be in their curriculum either.
You’ll NEVER get a Catholic to admit to hypocrisy to where their church is concerned.
