Being able to recognize subjectivity
Subjectivity is the concept that when it comes to certain things that there is no right or wrong, there is only opinion. Subjectivity and morality rarely mix. Just as there is no right and wrong when it comes to favourite colour or favourite food, such applies to many aspects of life that society tends to forget are completely subjective.
I talk a lot about projection. I believe that all human's disagreements/differences root to projection. The lack of ability to see subjectivity vs objectivity comes from the need to project. If you really think about it, there is no right and wrong when it comes to music taste, movie taste, clothing taste, etc. We tend to get lost in our need to project and forget that many of the things we demonize people for are still completely subjective.
Body type is subjective, style is subjective, politics are subjective, religion is subjective. The list goes on and on. When it comes to subjectivity, because there is no right or wrong there is no majority rules. Sure, majority rules will win an election, but that still doesn't mean the majority is right and the minority is wrong. Just because majority of society strive for a certain body type, follow a certain style, listen to a certain type of music, etc doesn't mean that these preferences are more correct than others. Doesn't mean that people in minorities of these preferences are in the wrong. Majority rules doesn't even mean that objective facts are correct.
It's important in life to check ourselves when it comes to believing our preferences are superior or that they are a right vs wrong. You don't need to slam someone for liking a type of music that is widely disapproved of, nor do you need to take personal offense to someone disliking your favourite music. This is the key to being able to peacefully and happily co-exist with our fellow humans. This is the key to ending bigotry. We don't have to agree on everything, we just have to respect everyone's right to their own opinions without getting upset about differing opinions.
