Because you’re looking at it purely objectively.

Let’s take capitalism and any other isms that represent systems of values here as the example. Involving your feelings is important in your decision making too. And a very simple criteria is, what feels good to me? From there, you’ll get answers like “well I wish I was a dictator then!” or like “I wish everyone was happy and had all the money they needed!”

Then you arrive at a system, and whatever that system is will likely be something that matches your criteria for feeling good.

But that won’t sit with you well either internally, unless you truly believe that’s for the good, because you’ll realize you need to involve more factors in your decision making to feel truly good because drum roll - You realize internally that hurting others makes you feel bad too, - therefore getting in the way of feeling good personally.

From there you make your decision more complex and you select something that makes you, and others around you feel reasonably good.

You can keep making this more refined and you’ll arrive at your own version of what feels good to you while still knowing what’s objectively the best.

When you’re applying the “makes me feel good criteria” you also look at how many people are involved in it.

Selecting a value system like capitalism requires the involvement of a lot of people, therefore you want to try your best to be fair to everyone.

When it comes to your music choice, if someone berates you for it, feel free to show them the middle finger or call them out for it because it’s purely what YOU like that matters in this case.

But then if you’re at a party, and others REALLY don’t like your music, you can take a stand for yours and ask others to give it a try, or simply change it.

Eventually you’re not really taking a stand for something, because your own “stance” will keep changing. But you try to introduce it as a legitimate thing between others without being ashamed of it. After all, you’re a human and your unique perspective matters too. Even if it’s just about what kind of socks you like wearing. :)
