Re: Why so much hate for descriptive character posts?
I'm not a fan of internal thoughts, etc., in player posts for a lot of reasons. Possibly the simplest is that you're turning a post, which should be primarily a thing for the GM and other players to react to, into a reading comprehension test. As a GM, I often miss things if they're in long player posts. As a player, much the same thing.
While rare, I've also had the same problem as others mention with the aggressive thoughts thing. Not fun to deal with. In general, the rule I run with in a game is that anything you put into your post is fair game for others to react to. If you posted thoughts, then it was more or less evident from your face and body language what you were thinking about.
I break the aversion in three ways, though. The first are solo games where sharing a lot of thoughts with the GM is perfectly fine - because all of it can be reacted to. The second are "journal" style threads within games where it's not cluttering up the main part of the action. Finally, I break it entirely for games like Eclipse Phase where non-obvious communications are a big part of the game's setting and source material (and the GM has an actor in the exchange, even if the other PCs might not).
