When any group blindly engages in the same unsupported speculation we call it a circle jerk.
If you want to talk about zimmerman's past conduct then let's include the time he bounced his girlfriend around and the time he tussled with a cop doing his job.
We can also talk about the things we do know from zimmerman's own mouth...he was pro-actively trying to close the gap between himself and martin (following)...martin was pro-actively trying to avoid confrontation (running).
The whole 'martin attacked zimmerman' scenario requires that in the space of less than two minutes martin completely reversed his action of avoidance to one of confrontation and that zimmerman did the same in reverse. There is nothing to suggest this let alone prove it.
In my book zimmerman is no hero, he's a dope who got in over his head and had to shoot his way out of the situation he initiated. I don't think he will be convicted or should be based on the evidence. His life is permanently effed either way but, the other guy is dead.
Martin may not have been anybody's idea of an angel but there's no indication that he was any worse than millions of American teenagers these days of all colors and economic background.
I live in one of the top ten wealthiest zip codes where I raised three daughters (now grown). I've seen more than a couple of 'good' families turn out kids a lot worse than what we know about martin. And, I personally know people who started off with far less of everything than martin had (except trouble). They took really scary detours before getting straight. One in particular is a First Sgt. with the 101st.
All that though is utterly meaningless vis a vis what happened that night. What does have meaning though, is the fact that there is absolutely no evidence that martin was doing anything that night except walking back to the place where he was staying...that zimmerman followed him by car and then on foot..and that martin took steps to avoid confrontation with the stranger who was following him --- he ran.
I’m not going to discuss the evidence with you right now. I find you to be an unreasonable crank. We come to opposite conclusions on the same evidence. Obviously, there is something different between how the two of us get from evidence to conclusion, but I really don’t care what you think; and I assume you don’t care what I think. IOW, neither one of us will be persuaded by the other.
That is exactly what happened according to DeeDee, Trayvon's girlfriend's own words given to the media about her cell call with Trayvon that night. I'm sure that the prosecution and the defense have a copy of this initial interview of hers before she started changing her story and dancing away from it.
