duty to retreat

Duty to whom??

You must have grown up in a nicer more enlightened neighborhood than I.

I understand the duty to retreat is fairy common. It is a duty to all of us, in order to reduce violence. Again, it doesn't apply to your home (or, perhaps, to your place of business).

My understanding of it is that if you have the opportunity to retreat, safely, with no risk of further injury to yourself (let's say if the other guy is on the gorund and could not run after you, you can't keep hitting him, rather, you have to walk away), you have to do so.

Whether or not you could do so safely is up to the jury.
