The facts:

1. Bitcoin would NOT have failed if Satoshi had chosen a 2MB limit rather than 1MB, to say otherwise exposes you for the complete idiot you would be. Therefore, any FUD about 2MB is laid bare as completely propaganda.
2. Adding 2MB now means nothing as far as the technology, network and platform is concerned.., refusing to do so is simply because you do not want to establish a precedent that you can increase the block size to address scalability issues. Why? because the necessity of a sidechain solution for scaling moves further down the road.

There is nothing else to talk about.
