To Mudcat moderators(whoever they may be)

Are there some subjects which not up for debate on this forum...like homosexual infection rates, abortion, creationism, rape, etc?

If this is the case then why is there not a list of prohibited subjects?
If it not the case and we are free to discuss any subject, why are some posters subjected to a torrent of personal abuse from a handful of other members?
You know who they are, it is cowardly to bury your heads in the sand while these people reduce civilised debate to a hatefest.

Either make clear which subjects are off the menu, or get rid of the abusers.
