Well, I suppose it would be anyone who considers themselves to have an actual sentient existence. Anyone considering themselves to be part of what WE consider “we”.
Mankind, for example. Medium article writers, maybe. And if there may be varying levels of existence (or perceived existence) between Christians and atheists (of which I was once one), then I invite you to take your pick. (They can’t be all that different….can they?)
I would be very interested in hearing your definition if it differs from mine. (I tend to go along with the dictionary pretty much on this one, in addition to the “collectively sentient” concept above.)
(We aren't going to get into, "What is a woman?", are we?)
