HP, I agree with those who say hold back. Your efforts will bear more fruit if you keep your cool and stay un-DAed/un-DFed. Keep the long range view in mind. Most of us can relate to wanting to vent our feelings about the org's corruption, but you will do more good if you stay "inactive." More options will be open to you. Think of others rather than your own feelings.
You state "I ... wondered if I should use it as a
tool to maybe wake up individuals as the BOE will have to read it." You won't wake anyone up with a DA letter. It's not a "tool" for that! If you remain inactive you will have multiple ways to enlighten people. DA letters have a long record of waking up NO ONE. All the "faithful ones" think of is "he went out from among us because he's not of our sort." That's it. They not only will not care what you say are your reasons, but they will be positively afraid of reading them. Why stir that up that fear? Isn't reasoning better? You will be able to reason with them if you can still approach them and talk with them. DA yourself and you will cut that off permanently. Think about it...
