I think the ladies of the Forum here are taking this stuff WAY too seriously.
I'm sure Bob doesn't really care about whatever it is as much as you think he does. If Bob gets Free Tickets to something he said he hates, like a MLS soccer game in (Insert City near him) he will probably go. Because at the end of the Day, he isn't doing it to express principles but to extract an exchange from you. (Conversation)
But mostly he wants an Engaging plugged in discussion about something. I think most women don't get it because they see it as conflict. (booo) and Most women simply don't have a horse in any race.
Whats your favorite (Thing)? She says, "Wellll......... um I don't really... BLAH BLAH BLAH... yadda yadda yadda."
What she means is, "I think that (Thing)'s are silly, but, I'm not going to hurt yer feelers so, I'll just play dumb and pretend I don't really know or haven't really thought about it, when the Truth is that I simply don't care."
Because in all honesty, they are tolerating this exchange in conversation. They don't REALLY care about what you might be interested in. They are waiting for the lead in the conversation so they can talk about whatever they care about. BUT Bob likes talking to women, but probably hates talking about Women-y stuff, so he becomes Troll Bob and picks on random things. HOPING to stir the Passionate side out of a woman, about something they can mutually get on board with.
The Irony is that men handle not caring about what women are talking about, very different than women. We simply tune out or, "Oh look a bird!" OR we throw you for a loop by doing some research and then POW! hit you with all kind of forbidden knowledge. But Women, pretend to care just enough, to throw us for a loop.
Which if you are Clutching a Joey Votto doll, this clearly doesn't apply to you concerning baseball.
