Hi!
I recall doing the same thing often and moreso when I was younger. I would categorize people and like you, just in my head.
I think is possible we do it because it makes us feel better about ourselves as we compare ourselves with another and so is sort of like a false boost.
I see things pop up in me which are hideous and thanks be to God we have help to grow.
As our minds are renewed/changed which is an ongoing process as we're in the bible, and praying, and learning, we change and grow.
Whatever it is that you are dealing with as regards this, bring it to Jesus, and tell Jesus how you do that and how you feel about these people and ask God for help in seeing others as He sees us/them.
We will always be having stuff in us that are battles, whether it be prejudice or anything at all, and so is a life long of growing and changing our minds on things.
The love chapter here might be good to read every day as it helps put in perspective about how to view/treat others. As well seeing how Jesus was with people in the bible also helps a great deal.
Here's that bit from the love chapter:
BibleGateway.com - PassageLookup: 1 Corinthians 13:4-7
4Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6Love does not delight in evil but rejoices with the truth. 7It always protects, always trusts, always hopes, always perseveres.
The above is a bit about how we love others, by doing or not doing the things given above.
These challenges will always arise. We'll be doing great and boom - meet someone can't stand and just all in our hearts and minds, and yet working with God through these love things, helps us to love as Jesus loves; even if only in our hearts and minds as person might never know how we feel; but we change inwardly and the outward also changes.
The very thing you are doing; sharing how you feel inside; is very good because by doing so, you are aware of how you are thinking on certain matters and it takes thinking about things and wondering why we feel that way to recognize it and to be able to change it if needs changing.
Television and school (peer stuff) has a great deal of why there are certain perceptions we have which are not good and not realistic. There are other sources as well, but those two are the big ones.
Take care and thanks for sharing.
There are several types of people that inside my head, I judge up one way and down the other. I don't like these people.
My mind makes a stereotype, and I bet most of the time a person I see isn't like what I assume they are like.
I don't ever say anything mean to their face, but inside my head I'm thinking how much I dislike them because of these certain characteristics,
most of which are physical appearances.
I'm not sure why I think that way.
At the risk of offending someone on here, I won't state what types of people they are.
How can I be less judgmental? I'm almost afraid of these people- seeing them weirds me out.
How can I figure out a way to look past the exterior at any good they have on the inside?
