Is it just a woman thing? Are they just fucking terrible at voicing their personal thoughts on things because of evolution or something? Men will sit and ramble about stupid crap for hours while building legos, fishing, whittling, painting Warhammer figurines, repairing a car, whatever. Intense detail, high focus, direct personal experience, the works. A statement of qualifications to discuss the subject.

Women will babble, too, but it's never... specific. Women get really defensive when nerds start grilling them on their nerd cred, or even just feebly flirting by asking what comic they like, what MMO's they've played, who their favorite Pokémon is, their favorite metal album, anything. It's like their social value is being challenged, and they have no ability to deal with it properly so they lash out.

A man behaving that way would be called thin-skinned and a retard. Just answer the question, Johnny, who's your favorite starter? What would your Patronus be? Hamburgers or pizza every day forever, and explain why.
