I think it's important to distinguish between a religion or ideal - say, Christianity, or democracy - and what people do under that name. If church X doesn't follow the clear teachings of Jesus, that doesn't reflect poorly on Jesus, but on church X. If nation Y has rigged elections, that doesn't reflect poorly on democracy, but on nation Y.
It is important to be able to ask theoretical questions like "is capitalism inherently flawed?" and separate them from "how is it being practised in this situation?" If capitalism + government meddling = failure, it's unfair to say that capitalism failed. Rather, we should say that capitalism wasn't practiced.
I think the poster is just asking for the same kind of logical distinction.
