The first rule of the Mysterious Vince Gray Support Group is that you do not talk about the Mysterious Vince Gray Support Group.

Or so says Ward 4 ANC commissioner Dwayne Toliver, a member of the MVGSG who sent a blistering email to its members today rebuking the “Judas’s” among them who spoke to The Washington Post about their recent meeting with the mayor.

The Post ran a pretty unflattering story Monday, with some Gray supporters anonymously dissing the mayor for being unaware of how his early missteps “have hampered his ability to effectively lead and have eroded his base of support.”

But they should have kept their mouths shut, says Toliver.

“Every member of this group agreed to maintain the confidentiality of our group’s information and comments. Do you really think that the Washington Post needs [to] use us as additional fodder for its cannons of crap incessantly aimed at Mayor Gray?” Toliver wrote.

Toliver tells LL that the tone portrayed by the Post‘s article was completely different from the actual tone of the meeting.

“It was very, very positive,” Toliver says. “Reading the article was a complete shock.”

Toliver was also peeved that LL had gotten a copy of his email, which he says was intended solely for members of the MVGSG. (LL’s boss checked with the lawyers; it’s fair use now, baby!)

Here’s the whole thing:

Good evening. To be polite, I was utterly outraged and disappointed to read negative comments attributed to purported supporters of Mayor Gray and his administration in the Sunday (5/22/2011) and Monday(5/23/2011) editions of the Washington Post. As we all well know, this working group was organized to, among other things, assist Mayor Gray in successfully implementing his stated policies, goals and directions for DC. Mayor Gray needs and deserves our support and assistance to effectuate those policies, goals and directions. However, a few disgruntled participants (who lacked the testicular fortitude to excuse themselves from serving on this group) took the opportunity to use comments and statements from our last meeting to publicly criticize Mayor Gray and his administration. Shame on you.

We live in a free democratic society. In addition,although we do not have voting rights, each of us enjoys freedom of speech. Your freedom of speech does not entitle you to betray the trust of those relying upon honest, well-intended supporters of Mayor Gray. Group members should not use any information, comments, plans or activities arising from our meetings and efforts to publicly or privately express their personal displeasure or disappointment in either Mayor Gray or his administration. Every member of this group agreed to maintain the confidentiality of our group’s information and comments. Do you really think that the Washington Post needs use us as additional fodder for its cannons of crap incessantly aimed at Mayor Gray?

The Judas’s among us should immediately summon the courage to withdraw from our group. Even if you intended your comments to be“constructive criticism” and/or believed same to be accurate, you obviously are either brimming with naiveté or lacking the requisite political acumen to foresee that the stupidity of those comments will do more harm than good to Mayor Gray.

Mayor Gray does not need me to defend him. He does need us to help him. Stay focused on our purpose, and everything else will take care of itself.

Thanks for your time.
