Why do people, including myself (because I have done it), assume things about people based on other experiences with similar people? An example would be the very common thing many girls/women assume about boys/men - they all lie, they all cheat. The reality of this, is they likely based that off of one or two bad relationships... There is no way of knowing if all men were like that unless you dated all of them. I can throw in my beliefs to this equation as many other "Christians" had looked down on me, judged me and looked at me in not so nice ways because of my tattoos and my piercings (I only have ears done now, but had lip,eye brow, tongue before). Since when does one's appearance have anything to do with God in that matter? As I have stated before, if you want to be judged, attend a church, apparently that is a very common thing people do to each other there. I choose not to attend any. People also assume I am that way (very judging) because of my beliefs, and I don't agree with judging a person based on anything, including a book. But again, because of a few encounters with people of the same beliefs, people choose to assume this of me... Which leads into... Another issue I have come across is people assuming I am the same way as the person/people I talk to/are friends with. My cousin is an example of a very "open/free" person, to say it politely... And when we were younger and hung out a lot together, many other girls and boys thought of me that way. They assumed I was like her because I hung out with her. I can go in another direction with another friend, she had a girlfriend in high school... because I hung out with her, people assumed I was a lesbian. As stupid as that sounds, it happened. I am far from innocent in this as I did this a lot when I was younger, as well. I guess it is a thing younger people do but I see adults doing this all the time (specially my own family). I try not to assume things in general because more often then not, the assumption is wrong. Like the old saying goes, don't judge a book by its cover. I guess this turned into a rant more than anything... lol But regardless... Why do people do this to each other? Is it easier to assume something of someone rather than actually taking the time to get to know them? I can't see it being more rewarding. TLDR : Why do people assume things about other people based on other experiences with similar people? aka judging a person based on the actions of similar people.
