Scott: This has been a circular argument for several years, and I can only repeat what I've said before.
Whenever people in any kind of club or society - social, vocational, even religious - meet, it's not uncommon for the discussion to stray from the ultimate topic of the club, with opinions on politics and other possibly controversial subjects. It would be a dull world if this didn't happen. Imagine a Meet where someone asks "did you see "Doc" Halliday's perfect game last night?" to be admonished "this is an Alpine club, not sports"?
Yes, even in a debate on a possibly touchy subject we should remember to be civil, and I've strayed from the straight and narrow path from time to time. I try to remember the admonition of Bertrand Russell (whom I admired in my young liberal college days; I even marched with him in the CND demonstrations for unilateral disarmament) that whenever someone stops rebutting the other party's argument with facts, and instead resorts to personal attacks, it's a sign that he's lost the argument.
One can disagree with another person, so long as everyone remembers the meaning of the word "debate." In a debate, or argument, one party advances a position, or point of view, and supports it with facts or data. The other party attempts to rebut (or refute - not the same) this by providing contrary facts. "I have to disagree with you, and here's why ... " or "I think you're wrong, because ... " This differs from a contradiction. As put very lucidly in the Monty Python sketch The Argument Room, "An argument is an intellectual process. Contradiction is just the automatic gainsaying of anything the other person says."
The password is condescending. If the general opinion of club members is that only Sunbeam - or at least automobile - topics should be discussed, then eliminate the Rants section, and also give notice that even in Chit-Chat anything not auto related will be deleted.
A lively debate, even on a controversial subject, so long as people remember the definition of the word, and keep civil, is not wasting one's time. It's even possible that people can learn something from it. IMHO.
