Why do W bosons only interact with left-chiral fermions and right-chiral anti fermions but not left-chiral anti fermions and right-chiral fermions?

I sort of grasp the notion of chirality but I can't quite comprehend why one is favored (left) with fermions?

Why does a W boson interact with an e-L electron and e+R positron but not e-R and e+L?
