To the contrary, I welcome criticisms my views in order to know whether they are correct or need adjusting. If you belong to a group in which everyone thinks the same, you will learn nothing. It's called groupthink. From https://www.investopedia.com/terms/g/groupthink.asp

Groupthink is a phenomenon that occurs when a group of individuals reaches a consensus without critical reasoning or evaluation of the consequences or alternatives. Groupthink is based on a common desire not to upset the balance of a group of people.

This desire creates a dynamic within a group whereby creativity and individuality tend to be stifled in order to avoid conflict.
