Prejudice, its used to describe what people have when they form an opinion about someone or something without beforehand having any knowledge, thought, or reason.

People like to believe they are smart, all-knowing and aware. They so blindly believe in their own capabilities that they often forget to do a reality check, how much do you actually know? how much are they actually aware and in control of? are they even in control of their own thinking and actions?

People always have their first impressions on new people they meet, that doesn't mean you should let that impression affect the way you treat them, give people a chance to prove otherwise even if it was a bad impression.

Some people have stereotypes against people, when someone meets a new person, person A looks rugged, has long hair, and his sitting posture very sloppy. They would immediately categorize them as a hooligan or "bad boy" and most would avoid contact as they don't like these kind of people and assume they wouldn't be nice people to talk or hang out with depending on the kind of people the judge's are.

Their assumptions were based on the looks of the person and through that assumption they think that person A probably talks like a hooligan. Person A never had the chance to prove otherwise, even before he opens his mouth his peers are already prejudging him without even getting to know him better. Is that fair? Shouldn't everyone have a chance to show who they really are?

I've been prejudiced often as well, people take a look at me and assume I'm of the "hooligan" sort and tend to distant themselves away from my or seem even "afraid" to talk to me based on my looks, I can tell, the people who really know me react very different from the people who don't. Why am I not given the chance to show who I really am? Before I open my mouth and share with you my views or opinions they are already judged and classified as the view of a "hooligan" and if the person is of the more "innocent" type, he would not give that view or opinion a chance and forget it right after.

Few are actually capable of reading peoples body language and choice of words or the way they speak. Even fewer are 100% right when they make that guess based on that. I however strongly believe whenever I make that assumption on someone, its definitely not done within the first few seconds of meeting that person but over the course of our interactions. So far in my new environment I've made my own guesses on people before knowing them, and even after knowing them, I realized I was right. They were really assholes and childish people.

Some are so narrow-minded that all they see is whats before their eyes, such as the looks of the person or the talking style, they are unable to look beyond the obvious and see what lies beneath, people have told me "if only your friends got to know you better, they would be in for a surprise."

And for those who are often prejudiced, those who actually dared to get to know you better before judging you are worthy of being your friends, everyone else are just naive people who speak before they think. They are a waste of your time and if you have to change their view/perception of you just to be friends with them, your naive one, thinking their judgment can be changed. They clearly trust themselves more than you.
Deep down they would still view you as whatever they want, not as what you are.

Open up your minds and be aware that not everything is as it seems.
