Don't say in comments what you wouldn't to someone's face.
It's very simple. Being very aware of internet bullying campaigns, youtube, facebook, there are people who are absolutely viscious. Fair enough you don't like something or someone but to use language like I would run her over and kick her (actually where they said they would kick her- I'm not going to print, it's too degrading but you can guess), I don't care how annoying their appearance or persona is, how are YOU even human? Having a blog, you can take things further, you can write paragraphs and talk about things on YOUR space but the internet also acts a great shield, the abuser suffers no real remorse for their actions.
