"So why can Zimmerman be afraid for his life and Trayvon can’t?"
It does not matter if Trayvon was afraid of something. As has already been pointed out, the record shows he went home but did not go inside. Instead he waited and went back to attack Zimmerman. He wasn't afraid. But it doesn't matter.
Being afraid of someone following you, even if Trayvon were afraid, is not a license to murder. You can only use deadly force in response to deadly force.
Checking to see where a suspicious person went, even following someone, does not carry a death penalty. Trayvon was not allowed to use deadly force against Zimmerman by bashing his head into the concrete. But by doing so he created a situation where Zimmerman was within his legal and moral right to use deadly force to save his own life. Those are the facts. You are repeating uninformed and irrational propaganda.
I’m not ignoring everything!
I did think he was 14, I posted that I stand corrected on his age.
Why did Zimmerman have a right to follow Trayvon, but Trayvon is not afforded the same?
Why did Zimmerman have a right of self-defense that you are unwilling to give to Trayvon?
Zimmerman got out of the truck to follow Trayvon: ok with you.
Trayvon comes out of the house to confront the weird guy following him: not ok with you.
