I absolutely don't think you should "have to flee".
But, in your home and curtilage, there is no legitimate "third option" - which is "stay out of trouble". If a zombie kicks in your door, the trouble has arrived.
On the street, though, there are many, many chances to walk into or stay out of trouble. When I lived in Brooklyn in the 1970s, I avoided trouble all the time. I never thought of crossing the street for 3 Trayvons to be "fleeing", and I don't think CCW should embolden you to walk into trouble you could easily avoid.
Also, see above. I think Zimmerman is innocent by common law and Florida statute from before SYG, his case is not an SYG case.

“On the street, though, there are many, many chances to walk into or stay out of trouble...I don’t think CCW should embolden you to walk into trouble you could easily avoid.”
You’re talking out of both sides of your mouth. I don’t care if a person is armed or not, they have to right to be and if a bad guy wants trouble then so be it, he gets trouble.
You are also taking the liberal stance that somehow a person with a gun is a wacko looking for trouble.
