It is a pretty sad mentality, but unfortunately this job..unlike any other.. is more of a life choice. (i guess you could equate it to a doctor choosing a hospital).
Since regional flying is so fluid, a regional coming into another's "territory" (current flying) is a man approaching your girl.

You're probably better off wishing for world peace than an end to this nonsense, but there is a light at the end of the tunnel. When we're all happily sitting at a major somewhere and it turns into "my major is better than yours!"
Or we become so indignant and just pretend like no other major carrier exists
Blue skies my friend.
