Good day for you today. For me as well. Right now I'm at my college, but the lecturer seems not to lecture.
Just getting curious (again).
Have you ever heard the word of stigma?
If not, then, stigma is some kind of labelling (negative one) people tend to put on you. Usually known as society stigma.

What I'm trying to pull is, our society might not be as noble as we think.

As the above picture shows, stigma follows some step stairs. At first we will gives subjective stereotype towards the subject, goes to an absolute division from us and the subject, it will worse when the subject loses it's social status, then further steps, total discrimination where from the discrimination born labelling.
From stigma, can turn into mental-illness for both the victim and the culprit.
A qualitative study was conducted and published in the British Journal of Psychiatry in 2004 about mental-illness caused by stigma. You can read it by clicking here.
As for the culprit, an abnormal fondness of bullying might appear and is considered to be a mental-illness.

My curiosity takes place here and there. If our society already chirping in the social media about not giving false-judgement, already conducted research about stigma and labelling, and doesn't like to be labelled themselves, why in the real world this kind of stigma still fly around freely and is treated as something common? Do we really enjoy disturbing one's mental health? Or are we hoping that no-one will put stigma on us while we put one on others? That is basically illogical. The universe reverts back to us, anything that we gives to it. In a very simple way, if you put stigma on a person, another people will give you stigma. Doesn't have to be right now or tomorrow. Maybe a year later, ten years later, or twelve years later. But, surely that is the fruit of your long-long actions.

So, to fulfill my curiosity, answer me my friend, why do you still give raw stigma on other people?
