Youtube is a great site in theory ruined by a terrible, retarded community. As are most websites that are allowed to have communities.
I don't blame the internet, I blame people. In the outside world people wear masks and on the internet these masks come off and seemingly decent people can reveal themselves to be truly despicable human beings.
The internet is a place you should always be cautious about when revealing things about yourself because you're exposed to the world and there is no code of ethics on the internet.
