\begin{definition}[Definition:Argumentum ad Hominem]
An '''argumentum ad hominem''' is a logical argument that concludes the falsehood of a statement because it is made by a particular person or group of people.
It can be argued that it is reasonable to be suspicious of an argument if most of the assertions made by said person or group regarding the topic under discussion are false.
However, such reasoning is still fallacious.
