Yesterday I read this article about two brilliantly sharp girls who started a hot line for females on their way home after a late night. The idea was a hot-line number that we could call and talk to someone while walking on misty roads.
I am not a fan of female self defence courses as they're merely a response to a problem not the solution ("An eye for an eye will make the entire world blind" - Gandhi). as long as we promote these kinds of courses as a solution females will continue being scared late at night., and it will only further feed the inequality between men and women.
On the other end of the scale is these two females solution to the problem of females being scared. Having a friendly voice on the other end of the line. In fact this line should not only be for females, it should be something for men too, as they're just as much a possible target for being knocked down on their way home.
