Mandy Patinkan who played the part of Inigo Montoya in the movie "The Princess Bride", makes a point of telling the Sicilian "Vizzini" played by Wallace Shawn "You keep using that word! I do not think it means what you think it means."
We improperly use words partly in ignorance and also in part because of a massive push from influential people with great publicity capability to create a kind of public opinion. Now I say "create" carefully, because in the truth of reality, public opinion cannot be "created" with the consent of each individual who as a whole make-up "the people".
Confused? So am I. Let's break it down to the basics.
In general terms: Mr. X. is the Public Relations officer in an organization whose purpose is to "protect the civil liberties" of Special Interest Group (SIG) "A". SIG "A" holds a belief that their civil liberties include the freedom to manage the finances of people whom they deem financially incompetent. So SIG "A" works to gain the trust of these individuals and persuade them to sign Financial Power of Attorney over to SIG "A" and SIG"A" promises to provide for their "needs" providing certain acceptable requirements are met by the individual (community housing, dining, utilities and sanitary facilities, etc).
Now that SIG "A" has gained some trust and "protected community" residents; SIG "A" decides to change what they see as the "needs" of the "protected community" residents. This is where Mr. X. must earn his pay by putting together a well articulated statement for why SIG "A" has changed the list of "needs" for which they will provide. So Mr. X's statement is going to say in basic terms that "Provisions 'b' and 'c' are not seen as 'needs' because of set of facts 'd'."
Now, if you caught this change from "needs" to "provisions", this is part of what I am addressing. The other part of my addressed issue is the changing meaning of words.
The word "cool" before the 1960's was used only in reference to temperature.
Now as to the post title, "Antagonism" means
"an·tag·o·nism/anˈtagəˌnizəm/Noun: Active hostility or opposition.Inhibition of or interference with the action of a substance or organism by another."So the sarcasm of the title is this: if someone is being antagonistic does not mean they hate something about the person to whom they are antagonistic. However, it could be argued that to hate someone or something about them would be antagonistic. So you see, it is the way that the title is composed that causes the sarcasm.
This understanding requires an understanding of the meaning of words. Let's learn more about what we hear and especially the meaning of the words we use!
The wicked plotteth against the just, and gnasheth upon him with his teeth. The Lord shall laugh at him: for he seeth that his day is coming.
