Silverstrata stop calling people you disagree with "stupid". A few of your own opinions are demonstrably wrong.
LHR does not have a lot of domestic, it is overwhelmingly international and this is anything from a Fokker 70 / A318 to an A380, often using the same gates, split Left and Right for the smaller aircraft. There are no "short" runways at CDG, they land on the outer and depart on the inner as per LAX.
IAG runs a two hub strategy, South American focus at MAD, North American at LHR, it's already fixed.
Lord Foster is not an " idiot". Can I ask, what part of aviation are you in and how did you miss the sight of the B744 landing on the outer runways at CDG?
