justify a wrongdoing

1. What is an ad hominem fallacy?

  a. This is a case in which someone argues for a claim based on an emotion that is irrelevant to the question at hand, such as pity or fear.
  b. This fallacy occurs when someone uses an equivocal or ambiguous terms in one of its senses in the premises of an argument and in the other sense in the conclusion.
  c. The fallacy is also known as the “slippery slope” fallacy–this is when someone arrives as a desired conclusion by making an illegitimate leap from an uncontroversial premise to additional related premises which do imply the conclusion but are not themselves justified.
  d. Rather than evaluating and critiquing what an argument says, someone guilty of this fallacy attacks the person making the argument.
  e. This common fallacy occurs when someone tries to justify a wrongdoing by pointing out that another person has done exactly the same thing and not been called out for it.
