Logical reasoning from Daily Kos

The following is a logical equation that davefromqueens, in the Daily Kos:

Bush Harbors Bin Laden, Funds Killing Of US Troops

Long ago in 7th grade Math, I was taught that if A equals B and B equals C, then
therefore A must equal C. So here are two simple logic problems. Logic Problem
One:

A. George W Bush funds and supports the government of Pakistan.

B. The government of Pakistan provides Osama Bin Laden with safe harbor.


Conclusion: George W Bush provides Osama Bin Laden with safe harbor.

Logic Problem Two:

A. George W Bush provides financial support and friendship to the government of Saudi Arabia.

B. The government of Saudi Arabia (not Iran) is the primary financier of "insurgents" in Iraq.


C. "Insurgents" in Iraq are killing American soldiers.


Conclusion: George W Bush is providing financial support to "insurgents" in Iraq who are killing American soldiers.

Despite the obvious fallacies and inaccuracies in davefromqueens' reasoning, we can easily display the absurdity with a parallel argument:


A. davefromqueens writes for DailyKos
B. DailyKos wants the U.S. to pull out of Iraq immediately
C. More Americans will die because terrorists are emboldened by America's withdrawal from Iraq.
Conclusion: DailyKos and davefromqueens kill Americans
Just as I don't believe davefromqueens' tautology is in any way accurate, neither do I belive the logic employed can be used to prove anything.

Also, let's not forget the argument from fallacy:

If P, then Q.
P is a fallacious argument.
Therefore, Q is false.
Or, to get really technical, we can invoke the association fallacy (I studied Logic in college, but God, I love Wikipedia)


An association fallacy is a type of logical fallacy which asserts that qualities of one are inherently qualities of another, merely by association. The two types are sometimes referred to as "guilt by association" and "honor by association." Association fallacies are a special case of red herring, and are often based in an appeal to emotion.

- The Nazis supported eugenics. Nazis are evil. Therefore eugenics must be evil.
- Adolf Hitler was a vegetarian. Adolf Hitler was evil. Therefore vegetarianism must be evil.
- Clinton was a Democrat. Clinton was unfaithful to his spouse. Therefore all Democrats are unfaithful to their spouses.
- Osama bin Laden is opposed to the invasion of Iraq. Osama bin Laden is a terrorist. Therefore anyone opposed to the invasion of Iraq must be a terrorist.
- George W. Bush supports the invasion of Iraq. George W. Bush is a Republican.
Therefore all supporters of the invasion of Iraq are Republicans.

Finally, to beat this horse to death, we can even view davefromqueens' argument as Non sequitur:

If I am a human (A) then I am a mammal. (B)
I am a mammal. (B)
Therefore, I am a human. (A)

So what's the moral of the story? Well, for starters, nothing is simple - nothing. Certainly not the war in Iraq, certainly not the global war on terror, and certainly not a string of platitudes meant to incite people to a false conclusion and ridiculous sense of self-righteous moral (or logical) superiority.
