That's nice, but she cannot speak for all women. There are some women who will give negative cues before you even say a single word but warm up to you when you've shown some personality. In fact, some women may appreciate the fact that you weren't scared away by a bitchy attitude in the first 5 seconds of the interaction and actually tried to get to know them.
<sigh> Know how I said to read the comments, because every argument you could think of would be covered there?
Here's what I don't get. I assume you are a heterosexual male. Please correct me if I am wrong; everything follows from this assumption.
As (I assume) a heterosexual male, I would think that you are interested in what women think. How they view the world. What they think about you, as a heterosexual male. How you can make them feel good instead of bad. (I assume you do not want to make them feel bad, on the whole. If you do, well, that's a different problem.) What if I told you there's this place on the internet where women talk to each other about exactly these things, and you can go and sneak a peek about what they're talking about? Well, here's your chance. Over 1000 posts by women, talking about just this thing: you coming up to them as a stranger and initiating conversation. You could go and investigate what they really think!
But you don't. You read the article and automatically assume that THIS woman is crazy, THIS woman is unlike any woman you've encountered, and she hasn't thought about X, Y, or Z that makes YOU different. Why don't you go and find out? Read those 1000 posts by the gender that you are interested in; find out what they think?
I don't for a second think you'll do it, so I'll mention some things that are covered.
1. Context is everything.
a.Location, for instance. It's okay to hit on women at bars, clubs, etc. She knows that's one of the things that happen at those places.
b. Body language, for another. Over and over, the women talked about what their body language looked like for "willing to talk" versus "unwilling to talk." Guess which one is which?
*hunched over, earbuds in, reading book, looking out window
*Looking around, smiling, making eye contact
c. YOUR body language. Specifically, mentioning something in a way that ensures that if she doesn't want to continue the conversation, she doesn't have to. Examples? Complimenting her shoes on your way off the bus. Telling her you've read that book, too, and then turning away to read your own.
2. No, really, about that earbud and reading thing. <---- That means don't talk to her. None of the women wrote in to say "When I'm reading with headphones, I like people to interrupt me!" On the contrary, they talked about using it specifically as a way to tell people not to talk to them, but that people were always interrupting them anyway. One man wrote in to say that, wondering if this was true, he paid attention on the bus the next morning, and holy christ! it was true. A kid with Asperger's wrote in advising them that he did the same thing, and the only book he'd found that actually worked as a deterrent was the Bible. They honestly thanked him for the tip.
3. Over and over (I keep saying this, because you seem to think it's just this one woman, but really, the same things were said, over and over, by different women) the women talked about conflict avoidance and keeping the situation from escalating. You know how lots of 'em said they did that? By smiling and pretending to be interested, so that the man in question didn't get angry and start screaming at them. Men wrote in, saying "why can't you just be direct?" and they laughed at these men. Apparently men who will disrespect one boundary (body language) and then a second (polite reply and looking away) don't care much about screaming at them in public.
I know this is hard for you, because I really do think you want to make women feel good, not bad, but what if--what if-- some of those women you refer to, the ones who "warm up" when you don't pay attention to their signals, ie, them being "bitchy" (nice revealing use of the language, there--not talking to you = bitchy), were just trying to make sure you didn't follow them off the bus/scream obscenities/assault them?
What if? Assume for the moment that this is the case. How does that make you feel? Don't say "that can't possibly be it!"-- assume that what these women said is how they really feel. Take them at their word. How does it make you feel?
