OK - time to stop being a liberal

I have had a bit of criticism for allowing a particular comment on my blog. I used to moderate comments but then thought it was a little illiberal, to be in favour of free speech, unless people were saying stuff I didn't agree with, or approve of. So, reluctantly, I have turned my comments moderator back on. I have no idea how to remove comments, so if someone can instruct me I will do that too. So, sorry Ms/r Anonymous, from now on, like me, you will have to own your comments.
