Being neither divine nor Santa Claus, your humble editor is not omniscient. If there is a comment you believe is offensive and should be removed, your should send an email to him. The address is above. If you have not made an attempt to contact the editor directly about problematic comments, there is no need to complain about his perceived lack of action or to form the conclusion that he is not going to address the issue. He may simply be unaware of it.
Enjoy your open line.
