Growing up and even now, I have a problem of going into extremes. In my early teens, I was so obsessed with religion that it started to become a problematic part for those around me. Now, I am kinda "anti-theist" (in secret though, I wanna be safe). I used to be very homophobic. When I discovered that I fall in love with a guy, I have became so scared. Now, I am comfortable with my bisexuality though but will be in rage if the word "gay" is used as a joke.
I also rush to take a label for me that I am this, this and this, and get myself limited to that specific identity.
Although I am now on my way to develop the acceptance of the fact that I can be wrong, I still feel that I have not gotten rid of my extremism.
How to be a person who does not rush to take labels?
Legitimately congrats on being self aware enough to realize this is a problem you have, plenty of people never do. If you haven’t considered and have access to therapy that could help.
I would also say just learning more about different perspectives and ways of being helps kill extremism. You can not believe something but also try to understand the minds and experiences of those who do. Even if your conclusion is still ‘they are wrong’, you can at least understand what about their life and experience leads them to their beliefs, and extend to them the understanding that they are also people doing what makes sense to them according to their experiences.
