mmmm kay.  Let's try to keep it technical, please.

2MB is a limit that has been discussed as a viable next-step, meeting with
the most consensus.

2MB gets beyond the 1MB hard fork issue, while still remaining within a
safety cap that should ensure the system does not go "off the rails" as
some has predicted.

Security, privacy and centralization are not going to disappear at 2MB.

Further, a limited step gains valuable field data for judging whether
further steps are warranted - thus informing the "better block size
solution" development process.

Finally, as stated in the initial PR, it is intended as a viable fallback
should we reach a point of criticality where the user community feels a
block size increase is warranted, yet cannot reach consensus on a fancy,
all-consuming solution be it 20MB, flexcap, BIP 100, BIP 102, etc.

I am open to suggestions for improving BIP 102.  The goal is a minimum
complexity fallback that others have previously agreed was a useful
kick-the-can compromise - a static 2MB cap.
