Authentic

In a loose sense, an authentic person is one who lives up to her own belief system. Putin is an authentic fascist, although he doesn't know it. Trump is an authentic narcissist, although he doesn't know it. Bernie is an authentic democratic socialist, and he does know it.  

I don't think authenticity is rare. We respond to it favorably much of the time. People who are painfully inauthentic (DeSantis, Nixon, Ted Cruz, Nikki Haley, Pence, Marco Rubio) may or may not attract enemies, but their friends don't like them (Oscar Wilde).
