And since we haven't seen any indicative proof we can't be certain, can we?
Um, no -- I'm not talking about indicative proof right now. I am speaking specifically around the subject of the overhanging sponsons. You have not acknowledged or accepted (or even disputed if you disagree) the fact that at this stage of construction, expecting the side overhanging sponsons to be mounted is not logical, given they have yet to even finish the hangar deck level yet.
If you really wish to use the overhanging sponsons as an arbitary yes/no line for determining whether it is a carrier, then that is fine -- I don't have an issue with it, but expecting it at this early stage of construction and then saying "it isn't there, therefore it cannot be a carrier" is pretty poor logic, don't you think?
