>There are common definitions of what words mean.
What are they? People assume their definition is common, but everything is much less clear than that. This causes frequent disagreements, and it's best to get more information.
>There is no need to put another label on it randomly, just call it what it is, picking up a quarter.
There is no need for me to label the action at all unless I'm in a position to explain what I mean. My position on the action is primarily private. Changing the definition is more useful in the other direction, when you call someone a thief I don't assume I have any idea what they did or what kind of person that makes them.
>Everyone (or at least majority of other people) thinks a thief is a bad person.
Using such labels to judge an entire persons worth is ridiculous in a number of ways. There are too many ways that both of us would consider innocent that can get you labeled a thief. I was almost booked for stealing $40 of gas after realizing I lost my wallet after filling the tank. Am I a bad person because of that?
>So I can just go around calling you a rapist right?
This started as me labeling an action as theft. If I walked around blindly calling people thieves I would expect the misunderstanding to cause problems for me.
