A mashal is not supposed to prove something – it’s meant to open your mind to another perspective by comparing the situation to something else. Sometimes it’s helpful to take a step back and see things from a different angle.
On a second note, the CR is an awful place to try to prove or convince anyone of anything. That’s because the people who post here are by-and-large stubborn people who already made up their minds. My belief is that it’s still important to share thoughts because some things just need to be said in order to open people’s minds to the idea that maybe there is another perspective out there. Unfortunately, I have found that the chareidi world, as a whole, has closed its mind so tightly that we have lost all perspective – there’s only one right way & I’ve got the monopoly on it! “Even” the great Torah scholars of our Mishnah, Gemara, etc understood & accepted the idea that it’s perfectly OK for others to disagree with me.
