I'll answer one and two in a simple way-
Do you know who Simon Cowell is? He's that british judge on American Idol?
Think of it this way, I'm like the Simon Cowell of the TMF artists, but I'm not british and I'm far friendlier than he is.
The point I'm making is that I'm like him in that I'm brutally honest. Its as simple as that. I have an opinion to give so I give it. As much as someone may like or dislike Simon Cowell he is consistant. He doesn't waiver, and he doesn't lie. Paula and Randy are like everyone else that comments. They pretty much say the same things over and over again and its gets redundant. And they sugarcoat. My bluntness counteracts the sugarcoating, in theory.
I think my dynamic here is alot how Simon's dynamic works with the other judges on that show. While we aren't judges here and this isn't a competition, I believe in evaluating people's art. Its there for a reason, and not just to look and admire. If and when I have something to critique I also have something nice to say about the artist's work.
As for why I cannot 'leave them alone', well, I would, but he started it. It is always someone else that cannot leave it alone and move on. If he could just take my opinion, and either agree or disagree in a peaceful and non-confrontational way this wouldn't have happened. I would have been satisfied and I would have only had to reply once.
If people want to reply and comment on my opinions, thats fine. But as I've said, there is a right and wrong way to do that. The right way has not been taken here and I'm almost certain the mods will agree.
