What you see as "vigilance", I see as annoying paranoia and a somewhat disingenious attempt to discredit those people through intimidation who have differing points of view to the IAM's party line.
Let's assume for the sake of argument that people are using multiple accounts... why do we attack the posters versus challenging their arguments and ideas? Frankly, My Dear Mister Roabilly's witch hunt of reviewing Black Magic's posts from 4 years ago left me not only less convinced of his accusations, but made me realize it smells of sickening desperation trying to find something by reading into something that does not pass the smell test of common sense.
Now Mr. Roabilly demands to know the names of people in this forum to "verify" they aren't the same poster? What might be that true motive, as to require this level of disclosure, as surely it could be that ideas and counter points would suffice? Might it be to create a level of harassment or create such a hostile environment for his union "brothers"?
Should Mr. Roabilly achieve his objective to expose Black Magic's identity and cause harm, I quote from that historical moment of Joe McCarthy's witch hunts:
"I regret to say, equally true that I fear he shall always bear a scar needlessly inflicted by you. If it were in my power to forgive you for your reckless cruelty I would do so. I like to think I am a gentle man but your forgiveness will have to come from someone other than me... Have you no sense of decency, sir?" -- Joseph N. Welch
Let's end this discussion of whom is whom, what's someone's "secret agenda", while attempting to limit debate within our ranks, and instead focus on the ideas presented, because if we cannot win in this simple online discussion, then we will never find success at the negotiating table.
