I know what the martial artists here mean regarding sparring with women. However, it's one thing to "hit her" or "arm-bar her" and another to "tear her bloody jaw off its hinges".
Honestly, I don't really think this would be a chink in the armor.
If the SHTF and you are in true survival mode, you will see everyone as being "resource hungry" and after your resources.
I'm fairly sure the whole point of this forum is to do our best not to let that happen.
It is instinctive to become xenophobic when resources are scarce. For those who don't have that instinct, be it man or woman, well they just be part of Darwin's theory...
Honestly, Rodion, I think your instinct would kick in.
My instinct is to serve and protect. I'm so screwed.
