admittedly, I agree with those who say the inappropriate comments on the internet is a cancer of our society. One of the reasons behind this is people confuse the idea of public and private. Many of them communicate on the Internet in their homes, which means they are mentally in public while physically in private. As a result, they might speak out their inner words on the Internet. Hateful speeches and cyber-violences could lead to real-life suicide, which can not be neglected by us. However, this is a great way for us to know our friends, colleagues, or even family members better. Seeing someone in his true colours can help us prevent unnecessary troubles.
