I am always annoyed by people's irrational preferences. I associate food preferences, e.g., "I can't stand onions," with childishness. Kids think things are gross. Kids think kissing and sex is as gross as tomatoes or Brussels sprouts.
Most of us grow out of thinking kissing and sex is gross, so why not the food thing?
I think I can honestly say that I have liked everything I have ever eaten as an adult.
If you are one of those people who gets grossed out by olives, you should consider developing a taste for them; it's part of growing up. Stop being a baby. It was cute then. It isn't now.
Preferences might come from our parents like everyone says everything else does.
But I've been thinking about that lately. How long are people supposed to or should be permitted to blame their parents for everything? 25. After 25, you have to start picking your own friends and thinking differently from how your parents do. Some people start earlier, and some start later, but after 25, you can't use your parents as an excuse anymore.
I know a lot of people who have people in their lives whom they call friends they hate because they grew up in the same neighborhood. Just because your parents bought a house next to some ass hole when you were 12 is no reason to stay friends with him. After 25, if you are still hanging around some racist piece of garbage you met when you were a kid, you need to reevaluate what's important in your life. It's part of growing up.
This goes for religion and politics, too. You can't say that yo vote republican or won't date black girls because it's the way you were raised. At some point, you have to employ your intellect and start doing the thing that separates us from animals: decide your own destiny. The shackles of your upbringing melt with just a little mental effort--way easier than mind-bending spoons.
So when a critical mind asks you why you hate coffee, and you can't reply with a slack-jawed "just cuz" or "I was raised that way," what will you say? Some give up an anecdote set in a much more recent past than childhood, but such anecdotal rambling is just as irrational as its slack-jawed cousins.
If you cannot think of a reason to hate pickles or certain sexual positions or the color purple, and you think you are a rational person in possession of a critical and curious mind, you should feel a great stress called cognitive dissonance. That feeling will go away when you either abandon your idea that you're smart or behave like a grown up.
Irrational preference does not make up for a lack of personality.
Before you email me:
If something hurts, you usually shouldn't do it.
Veganism is about ethics and health based on logic and reason.
If you are drunk or hung over or pregnant or otherwise physically impaired, you're excused. But when you join the breathing world again, you should join it as a full-fledged grownup.
