The first is: If you don't care to have a discussion on a given subject, do your best to not refer to the subject and ask your friends to do likewise.
The second is: If you are registered to be on another message board, do not make a request that this board be shut down. That really is a little selfish, don't you think?
Those who find any discussion on this board objectionable have a couple of options. Leave the board for the moment (or permanently) and/or use the ignore button that some of you cried for.
Just my opinion, of course.
