his library offers our visitors with a concise look at the common fallacies advanced today.  Some fallacies are rather easy to pick out; others are not so easy.  If you are new to apologetics, this is the page for you.  After reading the postings listed here, you will get an elementary but solid grasp of bad arguments so you can point them out to your opponent, and avoid them yourself!
The first and principal rule in dialogue is to maintain a certain degree of objectivity which, of course, precludes an unsubstantiated bias or prejudice towards a particular position.  Without such an elementary rule, society would collapse into anarchy.  Everyone would be concerned with what each believed or wanted to be the truth without a sober reflection on the facts of the matter at hand.  While it is an easy fallacy to detect, it is not as easy to correct in today's self-absorbed society.  In Christianity, the Protestant revolution is a perfect example of the facile acceptance of such a method of resolving disputes.  Indeed, the auto-demolition of Protestant Christianity continues, unfettered, year after year over this exact fallacy.
The ugly cousin of Subjectivism, the Argumentum Ad Populum - or "Appeal to Majority" as it is contemporarily called - is a common fallacy advanced by many today, particularly the leftist media.  You would think that in our advanced and enlightened society, we would be more intelligent in our reasoned discourse and public propositions.  Unfortunately, however, society is not getting smarter and smarter - it's getting dumber and dumber.  Newspaper commentaries are forever reminding Christians that their beliefs are "extreme", "rightist", "out of the mainstream", and not popular with the majority.
Surprisingly, this is yet another subjectivist fallacy that is bought hook, line, and sinker by the general population, despite cold, hard facts which contradict a proposition.  This fallacy is sometimes the "fall back" argument when all the facts have pointed in the opponent's direction.  It is the fallacy of "last-resort", and is commonly coupled with ad hominem attacks.  When someone has all the cards on their side (like the Catholic Church, for instance), the only thing left for the opponent to engage in is the mud slinging jingles: "intolerant", "bigoted", "backward", "cruel", "evil", etc. etc. etc.
Another subjectivist fallacy is what I like to jokingly refer to as the "Guido defense"; that is, sending over Uncle Guido to get your opponent to "see the light".  The threat of force – even subtly disguised – is hardly the use of reason, and of course, it need not involve physical force or violence, but any kind of measure which is intended to intimidate or browbeat an opponent into accepting the proposition under discussion.
