No where in that meme does it say they should have congratulated the teacher for that error. The point of that picture is not to encourage people to start congratulating people for their accomplishments and less criticism for the wrongs. Your interpretation of the meme is your own, but it’s not the intended interpretation.
It says, “The world will never appreciate the good you do a million times, but will criticize the one wrong thing you do. But don’t get discouraged” Therefor, the purpose is to teach strength. To teach people to not submit to the negativity of others. Stay strong and keep doing what makes you happy.
Your example, however, does not relate to the OP. Yes, they have the same idea is included where a person does many good things and is punished for the wrong. But the fallacy comes into play when the wrong thing they did was a crime. Of course someone should not be exempt from a crime simply cause they’re kind. Everyone should be treated equal in the situation of a crime regardless on your moral character. A persons crime history is what should determine the severity of ones punishment.
Lastly, you’re focusing too much on the history, realism, and purpose of the photo itself rather than the reason I gave for putting it up on the forum in the first place. I describe my reasoning for using that picture here underneath the picture, that is what should he the focus. No matter what the picture actually means or why it may have been used in the past or even why the picture itself is wrong, I still stated MY purpose for using and the message that I wanted people (devs specifically) to get out of it. Arguing about our own interpretation of the picture itself is pointless. I’ll take this no further as I feel I’ve adequately provided my purpose for this thread. Take what you will from it’s meaning but I promise you it has a positive meaning and purpose.
