There are a lot of things I like. My favorite book is The Sirens of Titan, by Kurt Vonnegut. My favorite movie is The Royal Tenenbaums, and my favorite album is Pink Floyd’s The Wall. I really really like all three of those things. But I’ve also met lots of other people who liked them that I didn’t particularly get along with.
In other words, the single data point of “Loves The Wall” isn’t enough to guarantee that I’ll like someone. No matter what thing you like, the same is probably true for you – liking that same thing isn’t, by itself, enough to ensure that you’ll adore that person.
So why assume the opposite is true?
Look, there’s also stuff I really dislike. Lots of stuff! But someone else liking that thing shouldn’t be enough to guarantee that I’ll dislike this person, that they have no redeeming qualities that I might find enjoyable or beneficial.
I’m not one end of a magnet, perfectly repelling all of one category and perfectly attracting all of another. Neither are you. Neither is anyone unless they’ve taken great effort to become so. Don’t carve out humanity so swiftly.
