I, personally, believe that internet anonymity should be maintained. That's because anyone who's bullied/ discriminated against in their normal life can go on the internet and not have anyone know who you are. I will say this, however: anonymity is often abused. An open request to the world: don't be a jerk. There's really no excuse. In real life, sometimes you just say something, but on the internet, you have the opportunity to review your words before you post. Please, there's enough hate in the world.
Back on topic, anonymity is not to be abused. If people were just a little bit more empathetic and read their message just one more time, suicide rates due to cyberbullying would take a nosedive.
