Some women are very wary about all men because they do not know who are the bad ones, and that is a very sensible precautionary attitude.
No, it isn't, the number of bad apples is very small compared with those who are perfectly normal and wouldn't dream of attacking or intimidating any woman.
The Taliban have a very similar attitude to you, women are always at risk (and a permanent temptation to men), so bundle them up under layers of clothes so no one can see what is underneath and as an extra precaution do not let them out of the house without a male protector.
A less emotive comparison, is that if you leave your house, you could be involved in a traffic accident, so never leave the house in case that happens.
A basic life skill from the start of time is an understanding that life is full of risks. Humankind could not exist if its earliest members hadn't done this in order to get sustenance to eat. A sign of maturity and wisdom is an understanding that risk is ineveitable in life and that we have to learn how to manage risk. One of those ways is understanding probability and being able to assess the probabilities of different scenarios.
If I leave my house, do not look where I am going and ignore any traffic signs or the presence of traffic, then I am unlikely to survive any but the shortest journey. If, when I go out I look about me, check for traffic before crossing roads, notice uneveness in the pavement and generally stay alert, then I reduce the level of risk and go about ,my business.
