When did I ever once say Cornish X or RSL were a breed? What I said was that hatcheries are pretty upfront when they are selling hybrid chickens, and that if you buy a breed of chicken from a hatchery, you're going to get that breed. Maybe not a good example of that breed, but that breed nonetheless.
I'm not sure why you are so in your denouncing of hatchery hybrids--or crossbreeds, if that makes you feel better--but they are wonderful chickens that aren't sold as something they aren't. And no one is going to get a random crossbred chicken from a hatchery masquerading as something else. If it's labeled a Faveroles, a person isn't going to get a Faveroles/RIR cross chick or something like that. Unless it's an Ameraucana, which I concede is horribly misleading.
And since everything I say seems to make you upset, I'm done here. Have a lovely day.
