Nietzsche suggests that individuals who openly express themselves and do not conceal their thoughts or feelings often provoke anger or resentment in others. By being transparent and authentic, such individuals may challenge societal norms or expectations, which can trigger discomfort or hostility among those who prefer conformity or maintain conventional beliefs. 

 Fair enough. I was thinking of someone I know who is without ego and extremely authentic. Authentic as a human being not as a thinker. People love him naturally.
