I don't have a problem with people who leave comments totally disagreeing with me, and saying that my point of view is totally stupid. I encourage constructive criticism, argument and debate. We're all entitled to our own opinions. I talked extensively about this in my post on Blogging and Politics. However, if you leave offensive or downright nasty comments that cause offence, or you use language that may offend me or my readers, I will delete your comment without responding no matter how good the rest of your argument happens to be.
