At this point I'd be surprised if MP is ever back in the proverbial saddle. It's just not realistic given everything that's happened.
If DT wasn't going to fire Mangini last year when Portnoy asked to be let back in the band, they sure as hell aren't going to do it now or years from now.
On topic: MP seriously needs to learn to pick his battles. I've never been to his forum, but it's notorious for the spontaneous deletion of threads that aren't in line with his views. Of all the posts to not only keep but respond to, he picks this one, while dropping some extraneous and unnecessary information which (either inadvertently or purposely) made DT look bad?
Let's say he did just say "I sent all the members of DT a congratulatory email." The objection is:
I'm sure that if he only said that he congratulated them personally everybody would say "AND DID THEY RESPOND YOU? WHAT HAPPENED?" and stuff like that, so it would very much be the same.
He's not obligated to answer that question. He doesn't have to say anything at all. If he doesn't respond people will just think he's busy, and he is a busy guy. This is just another example of MP not knowing when to keep his mouth shut.
