You left out the most important fact of the Marissa Alexander case: she left the room in which the confrontation was occurring, went to the attached garage, retrieved her handgun from her car, and then went back. There's also a question of whether it was a "warning shot" as she claims, or just bad marksmanship in trying to kill her husband, the facts strongly support the latter, and that's generally something for a jury to decide. Warning shots are also very strongly frowned upon for reasons that should be obvious.

So Florida's stand your ground law provision had absolutely nothing to do with the case. Plus there's one now pretty old study out there that shows in Florida that blacks successfully used the stand your ground provision of Florida law as part of a self-defense affirmative defense more often than whites. The claim that women are disfavored in claiming self-defense is literally something I've never heard of.
