Moderators of public forums, take note: rights do not come from having power but from being in the right. While you may have the power to delete all comments that threaten your position, you do not have the right to do so. Deception is immoral; and maintaining the false image that your forum allows dissenting opinion and discussion (as long as the comments remain friendly and decent), while deleting posts merely because they oppose your position—underhandedly, or without publicly posting your actions—puts you in the wrong. If you want to have biased discussions where toleration of dissent is limited or nonexistent, then declare that plainly in your rules. Take a look around the SBC Open Forum, and you will find that all deleting of comments and banning of participants has been accompanied by a public posting of the reasons—and no comment or poster has ever been deleted for merely having a position that opposed mine.
