"Now this is a load of bull. I am not unconsciously deeply sexist because I sometimes refer to women as girls. Complete rubbish." - I didn't say that you were sexist because you refer to women as girls. That's like saying "I have a cold because I'm sneezing" the sneezing is the symptom, not the cause. And the fact is, people approach women differently than they do men. That is why there is still gender inequality in our society. It is impossible to look at a woman, in a context where gender is theoretically irrelevant, and not think of them very differently than you would think about a man. Think about that in your own life. Now I know exactly what you'll say "No no no, not me. I treat everyone the same." But do you really? Again, I'm not questioning your intent. I don't think you're actually what we would call a sexist person in any way. The best way I can describe it is with the frequently used metaphor, in these contexts of the moving sidewalk. Sexism, is like a moving sidewalk that everyone is standing on. There are some people who actually are sexist, they're the ones walking in the same direction as the sidewalk, really quickly. Then you have the people who don't really think about sexism much at all and say "I'm not sexist". You're standing still on the sidewalk sure, but the sidewalk is still carrying you along. If you actually dont' want to be carried along by the sidewalk, you have to try to walk in the opposite direction. That's what we're talking about here.
