William's great joy in life is context-free invective. He never bothers to engage the content of the article, only flings insults at other commenters.
You should probably make sure that your comment excoriating someone else for making derogatory statements does not, itself, contain derogatory statements. Also, it took me longer than it should have to decipher "slithead." I had a crazy mental image of a person with an actual slit on the top of the head, kind of like a mail drop.
