As a great believer in freedom of speech, there are few things I won't allow to be published as comments on this blog. If you look through the comments you will see that I like debate, I encourage feedback and have a very thick hide!
However, if your comment is a string of abuse with absolutely no intellectual comment whatsoever, expect it not to be published. I guarantee you that I will take less time and effort deleting it than you will writing it in the first place.
