While I understand the sentiment behind your argument that we should not be offended by criticism about ourselves, I strongly disagree with the notion that all offense is merely a product of our own insecurity. It is true that sometimes our reaction to criticism can be rooted in feelings of insecurity, but this is not always the case. Oftentimes, people are offended by criticism because it is unjustified and rooted in prejudice. For example, if someone is a minority and they are subject to criticism based on their identity, they are more likely to be offended because the criticism is rooted in bigotry rather than any real fault of their own.
Furthermore, even when criticism is rooted in truth, it is important to remember that there is a difference between valid criticism and criticism delivered in an inappropriate manner. Even when someone is secure in their own abilities, they may still be offended by criticism that is delivered in a rude or condescending manner. In these cases, the criticism itself may not be offensive, but the way in which it was delivered is.
Finally, it is important to recognize that being offended can be a healthy emotion. Feeling offended can be a sign that someone is standing up for themselves and their beliefs. It can also be a sign that someone is standing up for the rights of others who are being treated unfairly or unjustly. In these cases, offense is not merely a product of insecurity, it is a sign of strength and courage.
All in all, while it is important to recognize that our own insecurity can sometimes lead to feelings of offense, it is also important to remember that this is not always the case. It is wrong if you claim that the only time someone is offended is when they are insecure about something.
