> It's like normalising conversations about sport or TV. "But I'm not interested in sport or TV" becomes an unacceptable view because "most people" are. So you should definitely pretend to find the latest reality show as interesting as the most recent ball game because otherwise you "have no social skills."
I mean, it depends. I'm considered pretty socially adept (I can be an asshole, but usually it's due to other character flaws like selfishness and impatience rather than poor social skills), and I don't like sports or most TV shows. (I watched fewer than 5 TV shows or movies in 2021).
In my experience, with small talk it's about finding a common connection. People bring up stupid things (like the weather, TV, sportsballs) in order to find a point of connection. If you don't like the things the other person likes (sports/TV), then just saying "I don't like X" without offering a follow up shuts down the conversation. Socially it signals "I do not want to connect, leave me be."
I like to follow up with "Oh, X isn't my thing, but it sounds pretty cool, especially the INSERT THING THEY MENTIONED. That's kind of like Y (thing I like); have you seen that? Are they similar?" You can affirm people's interest in things without faking an interest yourself.
That being said, most chaos apes are not consciously aware of why they're doing things.
Where it gets difficult is that it really SHOULDN'T be one way, but when the majority of your interests are things that most people don't understand, they can't ask you questions and use your interests to connect to you like they would for most people.
The rhythm of a conversation doesn't dictate that you have the same interests, but it does dictate that you ask each other questions to find common ground. If one person doesn't understand the other well enough to ask the right questions, things get lopsided, which is where I think a lot of geeks struggle, especially as the experience differential compounds over time as we have fewer proper give-and-take conversations with peers growing up.
