Sid is right. Individuals can do enormous damage to others by postings that don't include all the facts. The postings are never corrected even though the poster realizes his error. Any such posting should require moderator approval. The moderator should require all information before approving defamatory postings. That would require some effort by a moderator, but rcuniverse is a for profit corporation not a free service. They should share some responsibility for allowing wing nuts to post anything derogatory. After all, the vendors that pay rcuniverse are the people that are harmed. I was in business for 50 years before retiring. After a very short time you realize that some people would no be appeased by anything short of you committing suicide. And that when you didn't do anything wrong to begin with.
