There are some limits to what we publish and even though a few people may think all contributions are printed without care, there are some that are sent back for rewriting and others that don't see the light of day because they are defamatory, excessively nasty and abusive or downright untrue. Sometimes we have to delete comments on our Facebook page because they contain offensive language or unsubstantiated accusations, but that is a whole different story.
At the end of the day we try to be fair to all and give people the right of reply.
It is better to have robust debate than no debate at all.
