My goodness, it doesn't matter the statistical probabilities of risk in any situation – taxi, walking, someone you know, someone you don't know.
We know as women that there are risks in life – of course you'd teach your daughters some strategies for navigating them!
You teach your kids how to cross the road safely. You teach your kids basic First Aid. You teach your kids how to cut with sharp knives – not based on statistics or probabilities, or to 'fill them with fear', but to give them tools to use to take care of themselves.
Nobody says that teaching kids to look both ways before crossing a road is 'teaching them fear' – it's just smart to know.
Debating about what's 'more risky' is sociological theory. Parenting is practical love.
OP, your daughter has been through something horrible. You equip her with whatever she needs to feel a bit safer - and know that her confidence will regrow with time and with care. There is nothing wrong with giving her tools she can hold on to in moments when she feels vulnerable, and in so doing learn that most of the time she will be OK, but if something ever knocks her confidence she's not entirely out on her own with nothing to call on.
And more than anything else, she'll know that her feelings are valid, and she;'s being taken seriously and met exactly where she is by someone that loves her. That's worth its weight in gold.
