You are absolutely correct.
Even in the raw, predatory animal kingdom, animals are well-adapted to making an instant calculus regarding risk/reward. A big component is the instant assessment of "how much damage will the prey cause me?" Think about mountain lion behavior, for instance, the first curious scan to determine is it worthwhile? This is a key moment in the overall dynamic.
For women running, the calculus is quite simple and similar, and it's proven by the examples given above. By real women, on this thread we know they aren't trolls.
PLAN 1
Resist, strongly, immediately = nothing worse will happen than was ALREADY GOING TO HAPPEN, i.e. a homicidal maniac will attack anyway. At least he's going to get damaged, hopefully severely. Go down fighting and at the very least mark/injure him for easy ID and apprehension. But for the other 90 percent plus of sh1tty "opportunist" attackers/scum, the calculus has been changed. These stupid fVcks assume women are easy prey. Under our current sad current reality, it's a woman's task to signal to him "Rossoid, that's the worst idea ever, I will show you why..."
NET RESULT = 90 percent better. Many attacks averted, NONE worsened.
PLAN 2
Be meek, unassuming, try to exercise "avoidance" by walking away, no eye contact = arousal of hunter instinct, the sh1thead thinks, "she's afraid, I'm getting hard, I want to follow/abuse her..." etc. No disincentive. Quite the reverse, this ENCOURAGES aggressive assault. Meantime, the true homicidal maniac is not somehow "dissuaded" by consideration of feminine weakness.
NET RESULT = zero change in outcomes. ALL attacks will have bad consequences for the woman.
The what-if analysis demonstrates conclusively, that the best plan is a. to be ready b. to signal immediately readiness for a hard fight and c. hard fight.
calig, I love women who stand up for themselves, you sound hot! But I'm not going to approach you on a run, lol! Lucky for you indeed you had advanced parenting and see the benefits.
