If you say there cannot be such a thing as a woman who is into tech, that is prejudice. If you say that (generally) women aren't into tech, that IS NOT prejudice because you are NOT pre-judging.
So marincounty says he (I assume) has never seen women having monomaniacal focus on tech. He has seen men having that focus. He has seen such focus helping men careerwise in tech. And he has seen women more interested in marrying up than in careers. Stereotype yes, generalization yes, prejudice no. This is simply describing his observations. Just because someone says something that doesn't go along with "Grrl Power!" doesn't make it misogyny.
By the way, you can read up on the research by Professor Catherine Hakim at the London School of Economics showing how women are not so interested in careers, just as marincounty observed.
Secondly, when marincounty is describing that women should be not into tech and helpful for some aspects of his life, he's describing his own dating preferences! How the hell is that misogynist? What right do you have to tell him who he should like? And who on earth prefers hurtful women instead of helpful ones?
Finally, when marincounty describes successful women as scary, he is describing other men's opinions! He is NOT advocating for that position, in fact he worries that he might suffer from the same defect. If he thought this way of thinking were OK, he wouldn't have ended with "I hope this changes in the future".
Do you really think it's a good idea to down vote people for thought crimes when they deviate from orthodoxy? Do you think you should be in such a hurry to condemn people in this way that you don't even bother to read their posts properly before you write screeds shaming them?
