Completely, in my opinion. It is true that emotions are irrational and not something you can control, but if you believe in yourself and are comfortable with who you are (flaws and weaknesses included) there’s nothing anyone can say that will make you feel inferior, because you will be at peace with your own limitations already.

Then again We all have our areas of insecurity but we can work on them. No one can make you feel inferior if you think and believe that you are not inferior.
Thinking and believing we are not inferior makes it so. And no one can make us feel inferior unless we agree with them. Our agreement is our consent. It is all in your head.
