It's ridiculous to tell anyone to walk down a dark alley way alone, drunk and teetering on heels they can barely walk in because it would be anti feminist, victim blaming and giving into rapists by not doing so
... rather you are just making it very easy for any nasty person/people to do whatever they want to you by placing yourself in a position where you are unable to defend yourself and where there will be nobody to help you. Just common sense.
The reality is that there are lots of bad people looking for trouble and they are not going to disappear, when they are put away there will always be somebody else to replace them. It would be lovely to live in a world where we are free to keep our doors and windows open day and night, walk any street alone at any time, be free to wave your money and credit cards around for the whole world to see without being mugged etc... nothing wrong with working toward creating that world, very stupid to raise your children for that ideal world rather than prepared for the reality they will face in the real one.
It is not victim blaming to lock your house up best you can to keep intruders out, it is not victim blaming to avoid being drunk, alone and extremely vulnerable in isolated public areas at night, it is not victim blaming to hide money and anything of worth from potential muggers, it is not victim blaming to not wear headphones so you can hear anybody approaching you from behind, it is not victim blaming to teach your children to be aware of the world around them and to take adequate precautions to avoid unnecessary victimhood.
It is common sense to do everything you can to make it as difficult as you can for potential attackers attack you. Attackers, whether their motive is to beat you up for the fun of it, rape you or steal your stuff, will target the most vulnerable person in a situation they believe will give them the best opportunity to get away with it. Why teach your children to make it easy for them?
