I have a couple of stories to share, and you will see what I am trying to get across. If not, I will explain it after the stories.
Flashback to eight grade: We were reading a book that had little importance to me because it was one of those that had very little moral or intellectual value within it. I am just skimming the pages that we are required to read, and I notice that part of a word is covered in black marker. I ask the teacher what the entire word was.
She responded, “The word was goddamn.” Only the “god” part was crossed out.
I ask her politely why she decided to cross out the “god” (I am qouting “god” continuously for emphasis), and she told me that people found it offensive. Then I asked why did she ONLY cross out the “god” part, and she replied by saying that people found damn and god as one word offensive.
I went on trying to say why not cross out the entire word or none of it at all, and still, she said that people only found the “god” part offensive. After a few minutes of discussion on morals, I just dropped it because I realized that nothing was going to change her opinion, and a continuing argument would ensue a pointless hatred.
I chose the battle, and although I didn’t get her to change her view on the “goddamn” censorship, I could see I made her think about why she only censored one part of the word.
[Edit] This was not done in front of the class. There is not point.
My second story happened recently, on Tuesday of this week in fact. My english teacher decided to inform us on the Holocaust (which I found redundant because I already spent a considerable amount of time learning about it in previous years. His lecture reinforced my point).
His reason for the downfall of Germany following the second world war was the people were unhappy with the government and the left-wing politicians. There was absolutely no mention of the Treaty of Versailles and how it caused the German economy to plummet indirectly causing the rise of the National Socialist movement.
I chose not to argue with him due to two reasons: only one other person in the class would understand what I am talking about and the teacher refused any comment during his lecture. People tried to comment or question material they didn’t understand, but he shot them down.
Moral of the story: arguing with ignorant and/or stubborn individuals will not lead to them converting their opinion or even allowing them to consider the situation from a different perspective.
But if you have the ability to persuade OTHER people to reconsider their beliefs and view it from different angles, you should use your last remaining engery to demonstrate various opinions for them. As TC said, keep your prism polished.
