Meybe they are afread what others would think of their opinion. Well I can honestly say I meade this page when I was still in primary school and I wanted to be myselfe. In the real life at home pagina I was afread to toon people who I really was so I came here to be me and this somehow made me stronger because I saw that I shouldn't be afread to be me and now when I am in secondary school I don't care what people think about me. I am who I am :) That's just my answer.
Because most people don't know who u are. u have the safety of a screen in front of your face, and u don't have to look someone in the eye. It's all about identity. u can be anyone on the internet if u choose to be, whereas in real life people look at your face and judge you. I'm not saying that people don't judge online, but it's easier to in the real world.
They have a screen infrontof them on the internet. u don't have to see the person right infront of u u just have a monitor and a screen. In real life u don't have that. u are just face to face with them then. Honestly its easier to be tough on the internet for that reason.
