There is
no way of convincing the mentally ill that airplanes are not a threat to
them

A) They're already busy merrily posting arguments on other newsgroups.

B) The pilots themselves do a sufficient job of dragging discussions off-topic
to bicker about politics and social issues. Just watch.

C) Yeah, just like the news media, newsgroups devoted to a topic shouldn't post
anything bad about that topic. If we hushed up all the bad news we'd be just
like that nice Soviet Union and the Afghan news. Then we could all be happy and
censored. That's the ticket.

D) Learn to separate facts from opinions. Leave the latter out. How
refreshing that would be.
