The jury selection process only weeds out those people who are so far out of the norm that they would be considered extremists, in one way or another.
One thing I have learned in 18 years of police work is that juries are unpredictable. (And you can read the word "stupid" into that on some occasions.)
A "jury of your peers" does not mean a bunch of people who think JUST LIKE YOU when it comes to defending yourself, or anything else. If only things were that simple. It means 12 people who answered a series of questions the way the lawyers liked.
Self-defense, in this day and age, is EXTREMELY tricky business. I cannot stress enough how important the concept of avoidance is to the everyday person. When I am off-duty, I go OUT OF MY WAY to avoid conflicts with others....even to the point of having people threaten me verbally. As long as there is no physical attack, I let it go.
I am NOT going to trust my freedom to the people they put on juries these days. It's just not worth it.
