When I cross a parking lot at night and see a woman ahead of me, I do whatever I feel is appropriate to make her aware of me so that a) I don't startle her b) she has time to make herself feel safe/comfortable and c) if it's possible, I can approach in a way that's clearly friendly, in order to let her know I'm not a threat. I do this because I'm a man.

Basically, I acknowledge every woman I meet on the street, or in an elevator, or in a stairway, or wherever, in a way that indicates she's safe. I want her to feel just as comfortable as if I weren't there. I accept that any woman I encounter in public doesn't know me, and thus, all she sees is a man -- one who is suddenly near her. I have to keep in mind her sense of space and that my presence might make her feel vulnerable. That's the key factor -- vulnerability.

1. Men can confront men.

No one is suggesting violence. In fact, that's what we're looking to avoid. But sometimes, a man needs to confront another man or a group of men in a situation. When I'm out in public and I see a man hassling a woman, I stop for a moment. I make sure the woman sees me. I want her to know I'm fully aware of what's happening. I wait for a moment for a clear indication from her of whether she needs help. Sometimes, the couple will continue right on fighting like I'm just a hickory tree. Other times, the woman will make it clear she'd like backup and I approach the situation. I've never had to get violent. Usually, my presence alone makes the guy leave if he's a stranger, or explain himself if they're familiar. It changes the dynamic. That's why I always stop when I see a woman getting hassled in public. For any reason. I make sure any woman, in what could become a violent situation, one I may or may not be correctly assessing, feels that she has the opportunity to signal to me if she needs assistance. I'm a big brother to a sister so that response is practically instinctual.
