A theoretical woman would statistically not be of similar physical stature and so would not represent an equivalent force. Also, kicking in the nuts is not generally seen as grave bodily harm and you didn’t say anything else so there was no pressing of an attack that would indicate a reasonable fear of death or grave bodily harm.
OTOH, a physically fit young man that is taller than you that has already sucker punched you, knocked you to the ground, is straddling you this pinning you while reining blows to your head “MMA-style”, one of which broke your nose and your head is banging off of the concrete definitely represents grave bodily harm and an imminent reasonable threat of death.
Your playing the race card here is the only inherent race card in this conversation. There was no evidence that Zimmerman was racist, the media ran a black and white picture of Zimmerman because he is Latino and they wanted to play a black-white angle, and a color picture would’ve show the dude was at least part Latino. So they ran with Zimmerman as a white guy killing an unarmed black youth until they couldn’t. And on and on.
