Ridicule is a strong and soft word. Sometimes ridicule is irritating and intolerable, other times it is light-hearted and humorous. Ridicule takes many forms, but deep inside usually contains a form of advice. Sometimes it's senseless and sometimes it's not. It's commentary about what others perceive to be your flaws. Ridicule (in the general sense) points out what others think is wrong with you and your extensions (friends, family, possessions, thoughts, identity), as well as general weaknesses. Sometimes ridicule comes with implied suggestions of how you should be. That is how it takes the form of advice. That doesn't mean we should take that advice, but we should be able to hear it.
There is truth in the expression, ridicule strengthens the ridiculed.
In my opinion, many people seem to be extremely sensitive these days. What ever happened to "sticks and stones may break my bones, but words may never hurt me?"
Neuroscientists might tell you that emotional pain and physical pain are processed and internalized the same way in your brain. A difference between emotional pain and physical pain is that I don't think you can cause an immediately fatal blow with emotional pain (some would say there are exceptions, for example hearing certain emotional words or a certain combination of sounds can trigger strokes, cause heart attacks, feinting, etc.). I'd say, I think many people have a relatively low pain tolerance compared to their potential pain tolerance. This statement could be inciteful, and insightful.
So why do many of us fear or dislike ridicule sometimes? I think, in part, people have been legitimately conditioned to learn that what others think of us can hurt us. It can affect who we can hang out with, what jobs we get, and general opportunities. What others think of us can cause us to be outcast and punished. The reason we don't like to be "judged" is because it doesn't feel friendly when the judgement is negatively directed at something we cherish (and can make one feel insecure). This is especially true because what others think of us can affect what we think of ourselves.
I think it is important to judge and to prepare to be judged. But also, we shouldn't be afraid to change our judgements as we continue to weigh information.
I believe happiness is when what you think, what you say, and what you do are in harmony. The problem with an intolerance for ridicule is it can make us hesitate to speak our minds freely. When we are afraid to speak up we can miss opportunities for growth (in others and ourselves).
People need a good theory for creating knowledge, and to prioritize error detection and error correction. Objective truth exists– just because we can't pinpoint it doesn't mean we can't infinitely approach it.
I once heard "the person you are most afraid to contradict is yourself." Many people are afraid to be wrong or make mistakes. When you say what you think people WILL give you feed back. When you conjecture, expect criticism– and that's a good thing that promotes progress. Don't be afraid to weigh information and self-reflect. Most people are more likely to take bad advice from a good friend, than good advice from a perceived opponent. I strive to be the type of person who can recognize good information regardless of who delivers it.
Human connection can be a mechanism for stress relief. There are degress of human connection. Human connection can include time spent with family and friends, conversations, pieces of art, a touch, a hug, a kiss, or even sex.
Many people are very sensitive to certain kinds of pain and stress. Concerning ridicule, people may be overly sensitive because they crave more meaningful human connections to relieve the additional stress ridicule can otherwise cause.
