(A logical fallacy is a flawed pattern of reasoning.)
#1. Argumentum ad ignorantium - Fallacy that something must be true because it has not been, or can't be, proven false.
(If you can't prove that god doesn't exist, that means he must exist.)
#2. Argumentum ad misericordia - Appealing to pity.
(Why are you so intent on destroying something that makes so many sick children happy!)
#3. Argumentum ad nauseum - Fallacy that something is likely to be true the more often it is said.
(God exists, how many times do I have to tell you?)
#4. Argumentum ad novitatem - Fallacy that something is right because it's new.
(Of course Mormonism is the true religion, Joseph Smith is the most recent prophet.)
#5. Argumentum ad populum - Fallacy that something is correct based on the amount of people who believe it.
(Look how many people believe Jesus is the son of god, they can't all be wrong! )
#6. Bifurcation - Fallacy of presenting a situation as having only two answers.
(Evolution is wrong, so that means creationism is right.)
#7. Circular Logic - The premise that what you are trying to prove is evidence of itself.
(The bible is the word of god because it says it is, and it can't be wrong, because after all, it is the word of god.)
#8. Cum hoc ergo propter hoc - Fallacy of asserting that simulataneous events must be causally related.
(With all these natural disasters happening how can you deny that god isn't punishing us?)
#9. Plurium interrogationum - Fallacy of demanding a simplistic answer to a complex question.
(If god didn't create the universe then explain what did?)
#10. Slippery slope fallacy - Fallacy that one event will inevitably lead to harmful consequences.
(If we let lesbians get married it will be the end of family values.)
#11 - Tu Quoque. The fallacy that flaws in one thing can be justified by pointing to flaws in another.
(Well the US army also killed innocents!)
#12 - Argumentum ad hominem. The fallacy that personal attack and insult is a substitute for refuting what someone says.
(You are mad, stupid, lost your job, lied when you were 17… )
#13 - Red Herring Fallacy: An argument that is irrelevant and intended to replace the lack of real arguments or to replace implicitly the subject of the discussion.
("If God is cruel then how come he gives people eternal paradise?")
#14 - No true Scotsman Fallacy used to take advantage of the ambiguity of a word:
Scotsman A: You know, laddie, no Scotsman puts sugar in his porridge.
Scotsman B: Is that so? I seem to recall my cousin Angus puts sugar in his porridge.
Scotsman A: Aye... but no true Scotsman puts sugar in his porridge.
-The fallacy lies in redefining the word "Scotsman" in order to exclude those who put sugar in their porridge.
#15. Argument from (personal) incredulity.
("I cannot imagine how this could be true, therefore it must be false!")
