How often do you walk by someone and immediately judge them without asking yourself what their story is? Everyone has a story, and that story has played a big part part in making them who you see. Whether it's a rebellious teenager or a person with scars (big or small), they didn't just become that way.
So many many people, especially adults, will look at that kid in the mall with the pink spiked Mohawk, and the "weird" clothing and the facial piercings and think "how can their parents let them do that?" Maybe they don't have parents that are the greatest role models and maybe that kid is just lost and looking for a way to fit in. Do you think saying something like "wow how could you you do that to your body?" helps them? No, it doesn't. Actually it does the exact opposite. It makes them hate themselves even more and be less trusting of people. I'm no expert but i think that is something we need less of in society.
This brings me to my second example, some with scars. If it's a big scar that alters their appearance and the first thing you think when you see them is "They're ugly" Do you think they don't already tell themselves that everyday? Do you stop and ask yourself if they were abused, fought for our country and your freedom, or were the victim of a crime that someone committed because they got so angry at society they felt like it was their best option?
I'm not saying that none of you do ask yourself what their story is but to the people that don't maybe you should and think about it just for a second. Think about the damage that you can cause. would you want that to happen to you? Ultimately if you don't know what their story is you shouldn't be judging them.
