Different circumstances for Zimmerman.
Sure. But the statement holds true regardless. This is a binary. It is either OK to defend your life when attacked or it is not. It makes no difference who is attacking you.
In order for it to be ‘wrong’ we would have to abandon our most basic human right. The right to exist.
How so? I thought of the Zimmerman case, too. Man threatened with beating shots to defend himself. What’s different? Their colors?
