Assuming that you're being serious and not just joking or stirring the pot here, I think you're reading too much into this. People giving their favorite player a nickname or nicknames obviously doesn't make them "clinically insane" and shouldn't automatically be perceived as a slight to anyone else, unless the other person is directly referenced in the nickname. If King James has been fine for all these years, Queen Angel should be fine, too. Your personal (Double-Double) Queen can be Caitlin or whoever else you want. It really shouldn't matter.
Heck, I've caught myself calling Angel "Rebound Bae" a few times, because she cute and she gets them boards. One of the commentators for a recent Sun game called DiJonai Carrington "Honey Dijon," and that and "ThreeJionai" have both stuck with me. They're just nicknames. As a great man once said, that's all it is, and that's all it's gon' be. I can't and won't speak for anybody else, but for me, it has absolutely nothing at all to do with Caitlin and everything to do with the specific players being referenced.
