Salem Witch trials. Proof as it per se. Potatoes? So which incident involving potatoes was stated in my presence? Who is the witness to this? In and of itself; what evidence is any food item with someone waving it around assuming that I need to react to this individual waving something around as they are mad about the item they are waving around?
Analogies made that are mere comparisons based on a perspective. Lies to back them up.
Use of excessive force to prove their point because they can't get what they want done. Instead of reasoning they use force. Instead of following a flow of a debate; they yell.... and lie.
