Fi causes me to put myself in other people's shoes and think about how I would feel in that situation or how I would feel if someone I cared about was in that situation, sometimes it's not even a thought process, like I'll immediately just feel emotional pain seeing someone hurt an animal, or to look at a starving or beaten child, or to think about living through a natural disaster, or under a repressive violent regime...
It makes me want to value other cultures for what they are, and defend other people's right to be themselves, as long as it doesn't violate what I see as Universal Human Ethical Truths.
Because the universal human ethical truths are part of the Fi as well....certain things are just wrong, they just are, don't try to tell me it's subjective that owning human slaves or selling ones pre-pubescent children into prostitution is "just part of another culture." I love and admire and respect other cultures and try to see the world through their eyes....but there are violations to Universal Human Ethical Truths (that my Fi has determined) that I will not tolerate under any circumstance.
Also, it makes me really emo sometimes and very sensitive to the vibe and aesthetic of my external environment and/or how other people treat me.
