people reacting to situations is about individual. but we know every individual is unique and different. Team should be encompassing and not assuming. CEO or Project Director's boundary is only with the idea and not the individual.

Idea can be criticised, never individual. Your argument may sound right, but it is not considering everyone. Your argument is saying how one should react, but is not answering what if one reacts differently. How can we mend it.

Leader is one who is compassionate and has ability to differentiate idea from individual. Work is not entirety. Idea will never define a person. whenever we critique, it is best to keep it till the idea and never to person. my few cents.
