Take the following syllogism :
John believes that green people should be killed.
Mushmush is a green person, a neighbour of John.
Thus, John believes that Mushmush should be killed.
Formally, the argument seems valid. However, in reality it doesn't work. A persona can believe that all people with quality X should be killed, but not think it about a specific person he knows. So is there a logical contradiction here? What happens?
Thank you, Sam
