We in Blogville are all familiar with the comments, often mean and insulting left by individuals who won't sign their names. The internet is crawling with these trolls who think they're clever and so amusing.
If your comment is so witty, why won't you sign your name to it?
There are lots and lots of blogs on line. Some I don't agree with or find distasteful and so I don't read them. There are plenty of others to choose from. Sometimes the bloggers I like present an opinion I disagree with. I don't feel I have to leave a nasty comment in response. When I do comment, my name appears beneath it.
If you have something of value to say, then have the courage to sign your name and don't hide behind the word anonymous. If not, just slink back to the swamp with the rest of the trolls.
