As human beings, we're biologically inclined to make judgments, no matter what our type is, or who we are. We categorize things, and people, in order to remember and understand them better. Some people do this without even thinking about it. Some people probably secretly feel badly for doing it.
Much of stereotyping is simply due to environmental factors.
If you were raised from childhood in a nude tribe, you would naturally adapt. These individuals wouldn't leer at women, or even think twice about it. Then, let's take one of the female teenagers from one of these tribes, and place them in an American classroom. Of course, she comes to class topless.
The teacher would take action and make sure that the perpetrator was clothed immediately. The 'perpetrator' wouldn't understand why they were being clothed. They would attempt to remove the clothing, and be reprimanded. When explained why, they might not understand. ''Modesty? What is modesty? Why do I have to put this on? It itches, I don't understand.'' The teacher is frustrated, but adamant. Maybe she comes to class with holes cut out of her top the next day. But, eventually, she changes, and comes to have a superficial understanding of it.
People are naturally self-absorbed and intolerant. Often, when judgments are made on a cultural basis, they are emotionally biased judgments. Thinking about why you know what you know is necessary.
I myself am biased, because I go through life adapting. Where I stand will change based upon new information, new environments and new understanding.
I don't even think of the word, ''tolerant'' in an everyday context anymore. In every new situation, I think: ''Does it make sense?'' And, ''What do I need to do to understand this?''
Categorizing a group of individuals based upon appearance doesn't make sense. Each one is different, has different ideas, knowledge and a different perspective and environment that they have adapted out of.
Being cautious based upon preliminary data does make sense, but information when it comes to people is often unpredictable. That's why it's important to look at it on a case-by-case basis. Critical thinking.
