I've decided - suddenly, spontaneously - that this has gone on too long. Someone told me the other day he finds it 'depressing' to read the comments on this blog, and I have to agree. I'm not at all comfortable with the fact that some deeply unpleasant people are using it to promote their deeply unpleasant views, or that I have reached the stage of praying that some of my constituents don't read some of the comments, or that I decided against posting some pictures of Ugandan orphans performing at No. 10 because I thought it would attract abuse. Or, indeed, the fact that I'm almost self-censoring myself from writing about topics such as immigration or the Shannon Matthews case because of the comments that are likely to follow, which would be offensive and insulting to many of my constituents (who are the ones I really want to read this).
So, I'm going to moderate comments - reluctantly - from now on. And there are some people I just don't want on this site, and won't be accepting comments from.
