I don't know if you realize how hilarious that line is.
Unless you romance him, Solas doesn't see any modern Thedas races (dwarves, elves, humans, Qunari) as "people" either.

*Cassandra, Leliana, Harding, and Inquisitor all gathered around War Table, making final plans to follow a lead to Tevinter*
Cassandra: All right everyone, let's move out!
Inquisitor: Nah. I think I'm gonna sit this one out. *sits down*
Everyone: *stares*
Cassandra: ... Why?
Inquisitor: Because Solas doesn't see me as people. That means there's nothing I can do. *takes a swig of wine*
Leliana: But... you said he doesn't see any of us as people.
Inquisitor: Then I guess none of us can stop him. Let's hope that Abelas fella has this covered.
