Everyone is welcome to comment here, regardless of his opinion or perspective, and healthy debate is always encouraged. However, all comments must be gracious and free of insulting, crude, or unkind language. If I receive a comment that I believe makes a good point, but that does so in a rude way, I may choose to edit it or delete it at my discretion. If the sole content of the comment is name calling or sarcastic mockery, the comment will be deleted. Such comments are unproductive, not to mention unpersuasive.
