Also, people are different in different situations. People are different on youtube than they are on tumblr than they are on pinterest than they are on twitter than they are with their family than they are at the DMV than they are at a night club than they are ....
People aren't a personality attached to a name they're who they want to be at any given time and personalities change.
This kind of forced identity is not only dangerous for at risk individuals but is plainly anti-social and anti-human-behavior.
