On "taking sensible precautions":
All people, men, women, the elderly, whoever, should be aware that certain things might not be advisable. Things like getting so pissed you can't walk, wandering around a park in the middle of the night, flashing a large wodge of cash around in a pub and then leaving by yourself, leaving your car unlocked with the engine running and going into your house, etc etc etc. Common sense things. Everyone in society is at risk of assault, theft, being mugged etc, and everyone should understand about what they can do to minimise risk.
However if people do not follow the "rules" and something happens, it is the fault of the person who breaks the law.
On rape:
Most rapes are carried out by people known to the victim. Most rapes are not carried out when people are drunk. Women do not go around reporting people for rape because they have ill advised sex and regret it. Most women do not report rape because they know it is usually a waste of time. Women who get raped are the victim of a rapist. Because there is no way of telling who is a rapist and who is not, it is fairly pointless following all the "rules" as however hard you follow them, if you end up with a rapist and he sees his chance, you're still going to get raped.
If young women followed the "rules" to the letter, they would basically not be able to do anything. And they would still be raped. The "rules" are there simply so that when women get raped, people can find something that she did "wrong", and blame her for it. And think "well I'd never do that, so I'll be fine".
I have also spent an awful lot of time in all sorts of altered states with all sorts of people. I have wandered around London by myself as a teenager, all the time. No problem. When I was attacked, it was by someone I knew well and trusted, everyone was sober, it was lunchtime. What "rule" did I get wrong? Never be alone with any male you know including family? Silly.
The idea that women must restrict the freedom in this way is nonsense.
Teach everyone about common sense, fine. Don't single women and girls out. And don't look for reasons to blame them when they are raped.
