What NOT to say to a female solo traveller

I've been travelling around Australia for eight months now, five of which were spent in the outback. If that doesn't scream this girl can handle herself, I don't know what does. No I may not be the roughest, toughest backpacker to hit the roads of Australia, but I'm not pathetic either. Each time someone says something along the lines of "it's not safe for a girl to travel alone" I just ignore it. I've had men confess to me that they couldn't do what I was doing if they were a woman my age, fly across the world and explore a country alone, taking such a big risk. So what does that say about them? What does it say about me?
