Forum:Blue Eyes Deck Question

I have a Blue Eyes Shining dragon, and when it says Designates, I'm getting mixed answers. I also wonder why Stuff like Dark hole and lightning vortex destroy it, it doesn't make sense. I know they don't specifically desegnate monsters but, when it says destroy all monsters on the field, doesn't that card "DESIGNATE" ALL MONSTERS on the field, DESIGNATING Shining? If it doesn't why doesn't that count as Designating? It doesn't make any sense to me
