I had originally asked this at English.SE, but a quick disagreement with some of the users, including a high-reputation user caused me to lose faith in the English.SE community to even Identify the fallacy that I was talking about.
I too often see people apply a definition to something because both the thing and the definition share a same connotation, and not because the thing actually matches the definition.
Terrorists are cowards because they are evil.
This is a fallacy because "being evil" is not part of the definition of "coward".
The minimum wage is not Socialist because without it, many people will go into poverty.
This is a fallacy, because "not keeping people out of poverty" is not part of the definition of "Socialism".
I want to call people out on this kind of behavior, but I want to be able to do so without being confusing, so I am asking: Is there a word for this?
This is similar to Is there a name for the fallacy to appeal to connotation of an ambiguous term?, but I don't feel as though it's the same.
That question is similar but it seems to be more concerned with whether you use the connotation of a term to imply badness or goodness.
My concern has more to do with categorizing things into categories where they straight up do not fit.
